This bit enables the SYSREF processor, which allows the device to process SYSREF events (default: disabled). SYSREF_RECV_EN must be set before setting SYSREF_PROC_EN.

Set this bit to enable the SYSREF receiver circuit (default: disabled)

Set this bit to zoom in the SYSREF windowing status and delays (impacts SYSERF_POS and SYSREF_SEL). When set, the delays used in the SYSREF windowing feature (reported in the SYSREF_POS register) become smaller. Use SYSREF_ZOOM for high clock rates, specifically when multiple SYSREF valid windows are encountered in the SYSREF_POS register; see the SYSREF Position Detector and Sampling Position Selection (SYSREF Windowing) section.

Set this field to select which SYSREF delay to use. Set this field based on the results returned by SYSREF_POS; see the SYSREF Position Detector and Sampling Position Selection (SYSREF Windowing) section. These bits must be set to 0 to use SYSREF calibration; see the Automatic SYSREF Calibration section.

The SYSREF signal can be observed on the LSB of the JESD204C output samples when SYSREF_TIMESTAMP_EN and TIME_STAMP_EN are both set. Only supported in DDC bypass modes (i.e. D=1). This bit allows SYSREF± to be used as the timestamp input.

Activate DC-coupled, low-voltage PECL mode for SYSREF±; see the Pin Functions table.

This bit inverts the SYSREF signal used for alignment.

Adjustable feedback gain for CMLtoCMOS converter (high gain:1)

Reserved

When set, noise on VA11 is suppressed. It is recommended to have this set, as it reduces noise coupling from the digital circuits to analog clock, at the expense of a small increase in power.

Adjustable delay for the sampling clock (one hot encoded)

Returns a 24-bit status value that indicates the position of the SYSREF edge with respect to CLK±. Use this to program SYSREF_SEL.

These bits enable adjustment of the analog full-scale range for INA.
0x0000: Settings below 0x2000 result in degraded performance
0x2000: -5 dBm Recommended minimum setting
0xA000: -1 dBm (default)

When set, VA11 is used as the voltage reference instead of the band-gap voltage.

When set, activates the low voltage PECL mode for the differential TMSTP± input.

Enables the differential TMSTP± input.

Sets the pre-emphasis for the SerDes output lanes. Pre-emphasis can be used to compensate for the high-frequency loss of the PCB trace. This is a global setting that affects all 16 lanes (DA[7:0]±, DB[7:0]±).

0: RESERVED
1: INA is used (default)
2: INB is used
3: ADC channel A samples INA and ADC channel B samples INB (DUAL DES mode). A calibration needs to be performance after switching the input mux for the changes to take effect.

Calibration Enable. Set high to run calibration. Set low to hold calibration in reset to program new calibration settings. Clearing CAL_EN also resets the clock dividers that clock the digital block and JESD204C interface.

Some calibration registers require clearing CAL_EN before making any changes. All registers with this requirement contain a note in their descriptions. After changing the registers, set CAL_EN to re-run calibration with the new settings. Always set CAL_EN before setting JESD_EN. Always clear JESD_EN before clearing CAL_EN.

0 : Disable foreground offset calibration (default)
1 : Enable foreground offset calibration (requires CAL_FG to be set).

0 : Disable background calibration (default)
1 : Enable background calibration

Select the amount of averaging used for the offset correction routine. A larger number corresponds to more averaging.

Select the amount of averaging used for the linearity calibration routine. A larger number corresponds to more averaging.

Calibration status code

This bit returns a 1 when background calibration is successfully stopped at the requested phase. This bit returns a 0 when calibration starts operating again. If background calibration is disabled, this bit is set when foreground calibration is completed or skipped.

This bit is high to indicate that foreground calibration has completed (or was skipped).

0 : CALSTAT output matches FG_DONE.
1 : CALSTAT output matches CAL_STOPPED.
2 : CALSTAT output matches ALARM.
3 : CALSTAT output is always low.

This bit selects the hardware or software trigger source.
0 : Use the CAL_SOFT_TRIG register for the calibration trigger. The CALTRIG input is disabled (ignored).
1 : Use the CALTRIG input for the calibration trigger. The CAL_SOFT_TRIG register is ignored.

CAL_SOFT_TRIG is a software bit to provide the functionality of the CALTRIG input pin when there are no hardware resources to drive CALTRIG. Program CAL_TRIG_EN=0 to use CAL_SOFT_TRIG for the calibration trigger.
Note: If no calibration trigger is needed, leave CAL_TRIG_EN=0 and CAL_SOFT_TRIG=1 (trigger set high).

These bits adjust how long an ADC sleeps before waking for calibration (only applies when LP_EN = 1 and LP_TRIG = 0). Values below 4 are not recommended because of limited overall power reduction benefits.
0: Sleep delay = (23 + 1) × 256 × tCLK
1: Sleep delay = (215 + 1) × 256 × tCLK
2: Sleep delay = (218 + 1) × 256 × tCLK
3: Sleep delay = (221 + 1) × 256 × tCLK
4: Sleep delay = (224 + 1) × 256 × tCLK (default, approximately 1.338 seconds with a 3.2-GHz clock)
5: Sleep delay = (227 + 1) × 256 × tCLK
6: Sleep delay = (230 + 1) × 256 × tCLK
7: Sleep delay = (233 + 1) × 256 × tCLK

These bits adjust how much time is provided for settling before calibrating an ADC after the ADC wakes up (only applies when LP_EN = 1). Values lower than 1 are not recommended because there is insufficient time for the core to stabilize before calibration begins.
0: Wake delay = (23 + 1) × 256 × tCLK
1: Wake delay = (218 + 1) × 256 × tCLK (default, approximately 21 ms with a 3.2-GHz clock)
2: Wake delay = (221 + 1) × 256 × tCLK
3: Wake delay = (224 + 1) × 256 × tCLK

0 : ADC sleep duration is set by LP_SLEEP_DLY (autonomous mode).
1 : ADCs sleep until awoken by a trigger. An ADC is awoken when the calibration trigger is low.

0 : Disable low-power background calibration (default)
1 : Enable low-power background calibration (only applies when CAL_BG=1).

Set this bit to enable the CAL_DATA register to enable reading and writing of calibration data; see the CAL_DATA register for more information.

After setting CAL_DATA_EN, repeated reads of this register return all calibration values for the ADCs. Repeated writes of this register input all calibration values for the ADCs. To read the calibration data, read the register 673 times. To write the vector, write the register 673 times with previously stored calibration data. To speed up the read or write operation, set ADDR_HOLD = 1 and use streaming read or write process.

IMPORTANT: Accessing the CAL_DATA register when CAL_STOPPED = 0 corrupts the calibration. Also, stopping the process before reading or writing 673 times leaves the calibration data in an invalid state.

This register enables gain trim of INA. After reset, the factory trimmed value can be read and adjusted as required. Use FS_RANGE_A to adjust the analog full-scale voltage (Vfs) of INA.

This register enables gain trim of INB. After reset, the factory trimmed value can be read and adjusted as required. Use FS_RANGE_B to adjust the analog full-scale voltage (Vfs) of INB.

This register enables trimming of the internal band-gap reference. After reset, the factory trimmed value can be read and adjusted as required.

This register controls the INA ADC input termination trim. After reset, the factory trimmed value can be read and adjusted as required.

This register controls the INB ADC input termination trim. After reset, the factory trimmed value can be read and adjusted as required.

Small rounding errors may occur when subtracting the dither signal. The error can be chosen to either slightly degrade SNR or to slightly increase the DC offset and FS/2 spur. In addition, the FS/4 spur will also be increased slightly while in single channel mode.
0 : Rounding error degrades SNR
1 : Rounding error degrades DC offset, FS/2 spur and FS/4 spur

0 : Small dither for better SNR (default)
1 : Large dither for better spurious performance

Set this bit to enable ADC dither. Dither can improve spurious performance at the expense of slightly degraded SNR. The dither amplitude (ADC_DITH_AMP) can be used to further tradeoff SNR and spurious performance.

Time adjustment for bank 0 applied when ADC A is configured for 0° clock phase (dual channel mode). After reset, the factory trimmed value can be read and adjusted as required.

Time adjustment for bank 0 applied when ADC A is configured for -90° clock phase(single channel mode). After reset, the factory trimmed value can be read and adjusted as required.

Time adjustment for bank 1 applied when ADC A is configured for 0° clock phase (dual channel mode). After reset, the factory trimmed value can be read and adjusted as required.

Time adjustment for bank 1 applied when ADC A is configured for -90° clock phase(single channel mode). After reset, the factory trimmed value can be read and adjusted as required.

Time adjustment for bank 4 applied when ADC B is configured for 0° clock phase (dual channel mode and single channel mode). After reset, the factory trimmed value can be read and adjusted as required.

Time adjustment for bank 5 applied when ADC B is configured for 0° clock phase (dual channel mode and single channel mode). After reset, the factory trimmed value can be read and adjusted as required.

When set, the timestamp signal is transmitted on the LSB of the output samples. The latency of the timestamp signal (through the entire chip) matches the latency of the analog ADC inputs. Also set SYNC_RECV_EN when using TIME_STAMP_EN.

Note 1: In 8-bit modes, the control bit is placed on the LSB of the 8-bit samples (leaving 7-bits of sample data). If the part is configured for 12-bit data, the control bit is placed on the LSB of the 12-bit bit data (leaving 11-bits of sample data).
Note 2: The control bit that is enabled by this register is never advertised in the ILA (CS is 0 in the ILA).

0 : Disable JESD204C interface
1 : Enable JESD204C interface

Note: Before altering other JESD204C registers, you must clear JESD_EN. When JESD_EN is 0, the block is held in reset and the serializers are powered down. The clocks are gated off to save power. The LMFC/LEMC counter is also held in reset, so SYSREF will not align the LMFC/LEMC.

Note 2: Always set CAL_EN before setting JESD_EN.
Note 3: Always clear JESD_EN before clearing CAL_EN.

K is the number of frames per multiframe and this register must be programmed as K-1. Depending on the JMODE setting, there are constraints on the legal values of K (see KR).
The default values is KM1=31, which corresponds to K=32.

Note: For modes using the 64b/66b link layer, the KM1 register is ignored and the value of K is determined from JMODE. The effective value of K is 256*E/F.

Note: This register should only be changed when JESD_EN is 0.

Set this bit to 0 to request JESD204C synchronization (equivalent to the SYNC~ signal being asserted). For normal operation, leave this bit set to 1.

Note: The JSYNC_N register can always generate a synchronization request, regardless of the SYNC_SEL register. However, if the selected sync pin is stuck low, you cannot de-assert the synchronization request unless you program SYNC_SEL=2.

0 : Normal lane mapping (default). Link A uses lanes DA0 to DA3 and link B uses lanes DB0 to DB3. Other lanes are powered down.
1 : Alternate lane mapping (use upper lanes). Link A uses lanes DA4 to DA7 and link B uses lanes DB4 to DB7. Lanes DA0 to DA3 and DB0 to DB3 are powered down.

Note: This option is only supported when JMODE selects a mode that uses 8 or less lanes. The behavior is undefined for modes that do not meet this requirement.

0 : Use the SYNCSE input for SYNC~ function (default)
1 : Use the TMSTP input for SYNC~ function. TMSTP_RECV_EN must also be set.
2 : Do not use any sync input pin (use software SYNC~ through JSYNC_N)

Output sample format for JESD204C samples
0 : Offset binary
1 : Signed 2’s complement (default)

0 : 8B/10B Scrambler disabled (applies only to 8B/10B modes)
1 : 8b/10b Scrambler enabled (default)

Note 1: 64B/66B modes always use scrambling. This register does not apply to 64B/66B modes.

Note 2: This register should only be changed when JESD_EN is 0.

6 : D21.5 test mode
7 : K28.5 test mode*
8 : Repeated ILA test mode*
9 : Modified RPAT test mode*
10: Serial outputs held low
11: Serial outputs held high
12: RESERVED
13: PRBS9 test mode
14: PRBS31 test mode
15: Clock test pattern (0x00FF)
16: K28.7 test mode*
17-31: RESERVED

* These test modes are only supported when JMODE is selecting a mode that utilizes 8b/10b encoding.
Note: This register should only be changed when JESD_EN is 0.

Specifies the DID (Device ID) value that is transmitted during the second multiframe of the JESD204B ILA. Link A will transmit DID, and link B will transmit DID+1. Bit 0 is ignored and always returns 0 (if you program an odd number, it will be decremented to an even number).

Note: This register should only be changed when JESD_EN is 0.

Specify which comma character is used to denote end-of-frame. This character is transmitted opportunistically. This only applies to modes that utilize 8B/10B encoding.
0 : Use K28.7 (default) (JESD204C compliant)
1 : Use K28.1 (not JESD204C compliant)
2 : Use K28.5 (not JESD204C compliant)
3 : Reserved

When using a JESD204C receiver, always use FCHAR=0.
When using a general purpose 8B/10B receiver, the K28.7 character may cause issues. When K28.7 is combined with certain data characters, a false, misaligned comma character can result, and some receivers will re-align to the false comma. To avoid this, program FCHAR to 1 or 2.

Note: This register should only be changed when JESD_EN is 0.

When set, indicates that the JESD204C link is up.

Returns the state of the JESD204C SYNC~ signal.
0 : SYNC~ asserted
1 : SYNC~ de-asserted

When high, indicates that the digital block clock, frame clock, or multiframe (LMFC) clock phase was realigned by SYSREF. Writing a 1 to this bit will clear it.

When high, indicates that the multiframe (LMFC) clock phase has been established by SYSREF. The first SYSREF event after enabling the JESD204B encoder will set this bit. Writing a 1 to this bit will clear it.

When high, indicates that the serializer PLL is locked.

When set, the “B” ADC channel is powered down. The digital channels that are bound to the “B” ADC channel are also powered down (see DIG_BIND).

Important notes:
1. You must set JESD_EN=0 before changing PD_CH.
2. To power down both ADC channels, use the MODE register.
3. If both channels are powered down, then the entire JESD204C subsystem is powered down, including serializer PLL and LMFC.
4. If the selected JESD204C mode transmits A and B data on link A, and the B digital channel is disabled, link A remains operational, but the B-channel samples are undefined. For proper operation in foreground calibration mode, ADC_OFF in the CAL_CFG register should be programmed to 0x1.

When set, the “A” ADC channel is powered down. The digital channels that are bound to the “A” ADC channel are also powered down (see DIG_BIND).

Important notes:
1. You must set JESD_EN=0 before changing PD_CH.
2. To power down both ADC channels, use the MODE register.
3. If both channels are powered down, then the entire JESD204C subsystem is powered down, including serializer PLL and LMFC.
4. If the selected JESD204C mode transmits A and B data on link A, and the B digital channel is disabled, link A remains operational, but the B-channel samples are undefined. For proper operation in foreground calibration mode, ADC_OFF in the CAL_CFG register should be programmed to 0x1.

Program these register bits to enable extra lanes (even if the selected JMODE does not require the lanes to be enabled). EXTRA_LANE_A(n) enables An (n=1 to 7). This register enables the link layer clocks for the affected lanes. To also enable the extra serializes set EXTRA_SER_A=1.

0 : Only the link layer clocks for extra lanes are enabled.
1 : Serializers for extra lanes are enabled (as well as link layer clocks). Use this mode to transmit data from the extra lanes.

Important Notes:
1. This register should only be changed when JESD_EN is 0.
2. The bit-rate and mode of the extra lanes are set by JMODE and JTEST (see exception below).
3. If a lane is enabled by this register (and was not enabled by JMODE), and JTEST is 0 or 5, the extra lanes will use an octet ramp (same as JTEST=4).
4. This register does not override the PD_CH register, so the link is enabled to use this feature.
5. To enable serializer 'n', the lower number lanes 0 to n-1 must also be enabled, otherwise, serializer 'n' will not receive a clock.

Program these register bits to enable extra lanes (even if the selected JMODE does not require the lanes to be enabled). EXTRA_LANE_B(n) enables Bn (n=1 to 7). This register enables the link layer clocks for the affected lanes. To also enable the extra serializes set EXTRA_SER_B=1.

0 : Only the link layer clocks for extra lanes are enabled.
1 : Serializers for extra lanes are enabled (as well as link layer clocks). Use this mode to transmit data from the extra lanes.

Important Notes:
1. This register should only be changed when JESD_EN is 0.
2. The bit-rate and mode of the extra lanes are set by JMODE and JTEST (see exception below).
3. If a lane is enabled by this register (and was not enabled by JMODE), and JTEST is 0 or 5, the extra lanes will use an octet ramp (same as JTEST=4).
4. This register does not override the PD_CH register, so the link is enabled to use this feature.
5. To enable serializer 'n', the lower number lanes 0 to n-1 must also be enabled, otherwise, serializer 'n' will not receive a clock.

Select the mode for the 64b/66b sync word (32 bits of data per multi-block). This only applies when JMODE is selecting a 64b/66b mode.

0 : Transmit CRC-12 signal (default setting)
1 : RESERVED
2 : Transmit FEC signal
3 : RESERVED

Note: This device does not support any JESD204C command features. All command fields will be set to zero (idle headers).
Note: This register should only be changed when JESD_EN is 0.

DDC gain control.
0 : DDC filter has 0dB gain (default).
1 : DDC filter has 6.02dB gain. Only use this setting when you are certain the negative image of your input signal is filtered out by the DDC, otherwise clipping may occur.

This parameter defines the absolute sample level that causes control bit 0 to be set. Control bit 0 is attached to the DDC I output samples. The detection level in dBFS (peak) is 20log10(OVR_T0/256) (Default: 0xF2 = 242-> -0.5dBFS)

This parameter defines the absolute sample level that causes control bit 1 to be set. Control bit 1 is attached to the DDC Q output samples. The detection level in dBFS (peak) is 20log10(OVR_T1/256) (Default: 0xAB = 171 -> -3.5dBFS)

Enables over-range status output pins when set high. The ORA0, ORA1, ORB0 and ORB1 outputs are held low when OVR_EN is set low. This register only affects the over-range output pins (ORxx). JESD204C modes that transmit over-range bits are not affected by this register.

Program this register to adjust the pulse extension for the ORA0/1 and ORB0/1 outputs. The minimum pulse duration of the over-range outputs is 8 * 2^OVR_N DEVCLK cycles. Incrementing this field doubles the monitoring period.

This register sets the selection mode for the NCO frequency used in the DDC block. The NCO frequency and phase for DDC A are set by the FREQAx and PHASEAx registers and the NCO frequency and phase for DDC B are set by the FREQBx and PHASEBx registers, where x is the configuration preset (0 through 3). In single channel mode, the NCO selection method for DDC A in dual channel mode is used to set the NCO for the single channel DDC.

0: Use CSEL register to select the active NCO configuration preset for DDC A and DDC B
1: Use NCOA[1:0] pins to select the active NCO configuration preset for DDC A and use NCOB[1:0] pins to select the active NCO configuration preset for DDC B
2: Use NCOA[1:0] pins to select the active NCO configuration preset for both DDC A and DDC B
3: RESERVED

When CMODE=0, this register is used to select the active NCO configuration preset for DDC B In single channel mode, this register is ignored and CSELA must be used instead.

When CMODE=0, this register is used to select the active NCO configuration preset for DDC A Example: If CSELA=0, then FREQA0 and PHASEA0 are the active settings. If CSELA=1, then FREQA1 and PHASEA1 are the active settings.

In single channel mode CSELA selects the NCO frequency for the DDC.

Digital channel B input select:
0: Digital channel B receives data from ADC channel A
1: Digital channel B receives data from ADC channel B (default)

Digital channel A input select:
0: Digital channel A receives data from ADC channel A (default)
1: Digital channel A receives data from ADC channel B

Note 1: When using single channel mode, you must always use the default setting for DIG_BIND or the device will not work.
Note 2: You must set JESD_EN=0 and CAL_EN=0 before changing DIG_BIND.
Note 3: The DIG_BIND setting is combined with PD_ACH/PD_BCH to determine if a digital channel is powered down. Each digital channel (and link) is powered down when the ADC channel it is bound to is powered down (by PD_ACH/PD_BCH).

Sometimes the 32-bit NCO frequency word does not provide the desired frequency step size and can only approximate the desired frequency. This results in a frequency error. Use this register to eliminate the frequency error.

The default value of 0 disables the reference divisor and the NCO operates as a traditional 32-bit NCO.

Any combination of FS and FSTEP that results in a fractional value for NCO_RDIV is not supported. Values of NCO_RDIV larger than 8192 may degrade the NCO’s SFDR performance and are not recommended. This register is used for all NCO configuration presets.

When this bit is set, the NCO phase is initialized on the LMFC/LEMC boundary immediately after the rising edge of the SYNC~ signal (default). This feature works in 8B/10B and 64B/66B modes. This feature can be used to precisely align the NCO phase in several ADCs. In 64B/66B modes SYNC~ is only used for this purpose and does not affect the link operation.

After writing ‘0’ and then ‘1’ to this bit, the next SYSREF rising edge will initialize the NCO phase. Once the NCO phase has been initialized by SYSREF, the NCO will not re-initialize on future SYSREF edges unless ‘0’ and ‘1’ is written to this bit again.

Use this to align the NCO in multiple parts (without the need to restart the JESD link).
1. Make sure the part is powered up, JESD_EN is set, and the device clock is running.
2. Make sure that SYSREF is disabled (not toggling).
3. Program NCO_SYNC_ILA=0 on all parts.
4. Write NCO_SYNC_NEXT=0 on all parts.
5. Write NCO_SYNC_NEXT=1 on all parts. NCO sync is armed.
6. Instruct the SYSREF source to generate 1 or more SYSREF pulses.
7. All parts initialize their NCO using the first SYSREF rising edge.

The following description applies to FREQA0 thru FREQA3 and FREQB0 thru FREQB3.

The NCO frequency (FNCO) is:
FNCO = FREQA0 * 2³² * FADC
FADC is the sampling frequency of the ADC. FREQA0 is the integer value of this register. This register can be interpreted as signed or unsigned (both interpretations are valid).

Use this equation to determine the value to program:
FREQA0 = 2³² * FNCO /FS

If the equation does not result in an integer value, you must choose an alternate frequency step (FSTEP) and program the NCO_RDIV register. Then use one of these equations to compute FREQA0:
FREQA0 = round(2³² * FNCO/FS)
FREQA0 = round(2²⁵ * FNCO/FSTEP/NCO_RDIV)

Changing this register after the NCO has been synchronized is running will result in non-deterministic NCO phase. If deterministic phase is required, the NCO should be re-synchronized after changing this register.

NCO phase for configuration preset 0. This value is left justified into a 32−bit field and then added to the phase accumulator. The phase (in radians) is PHASEA0 * 2^-16 * 2π. This register can be interpreted as signed or unsigned.

When set, noise on VD11 is suppressed. It is recommended to have this set, as it reduces noise coupling from the digital circuits to analog clock, at the expense of a small increase in power.
