PRODUCTION DATA.
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
INPUT OR REFERENCE | |||
INAP, INAM | 63, 62 | I | Differential analog input for channel A |
INBP, INBM | 58, 59 | I | Differential analog input for channel B |
INCP, INCM | 18, 19 | I | Differential analog input for channel C |
INDP, INDM | 23, 22 | I | Differential analog input for channel D |
VCM | 16 | O | Common mode output voltage to bias analog inputs, Vcm = 2.0 V |
VREF | 15 | O | Voltage reference output. A 0.1-µF bypass capacitor to ground close to the pin is recommended |
CLOCK/SYNC | |||
CLKINP, CLKINM | 9, 8 | I | Differential clock input for channel |
SYSREFABP, SYSREFABM | 6, 5 | I | LVDS input with internal 100-Ω termination. External SYSREF input for channels A, B, C, and D |
SYSREFCDP, SYSREFCDM | 11, 12 | I | LVDS input with internal 100-Ω termination. External SYSREF input for channels C and D if output rate of channel A/B is different from channel C/D. Can be configured to trigger input for burst modes with SPI register write. Can be used as differential input or two single-ended inputs (SYSREFCDP becomes TRIGGERAB and SYSREFCDM becomes TRIGGERCD) for channel A/B and channel C/D. |
CONTROL OR SERIAL | |||
ENABLE | 14 | I | Chip enable. Active high. Power down functionality can be configured through SPI register setting and exercised using the ENABLE pin. Internal 51-kΩ pulldown resistor. |
SCLK | 3 | I | Serial interface clock input |
SDATA | 2 | I/O | Bidirectional serial data in 3-pin mode. In 4-pin interface, the SDATA pin is an input only. |
SDENb | 4 | I | Serial interface enable |
SDOUT | 1 | O | Serial interface data output |
SRESETb | 13 | I | Hardware reset. Active low. Initializes internal registers during high to low transition. This pin has an internal 51-kΩ pullup resistor. |
