SYSREF_EN |
0: Disabled
1: Enabled |
0 |
Enables the SYSREF mode. SYSREF_EN should be 1 if and only if OUTB_MUX = 2 (SysRef). |
SYSREF_DIV_PRE |
1: DIV1
2: DIV2
4: DIV4
Other states: invalid |
|
The output of this divider is fINTERPOLATOR. |
SYSREF_REPEAT |
0: Master mode
1: Repeater mode |
0 |
In master mode, the device creates a series of SYSREF pulses. In repeater mode, SYSREF pulses are generated with the SysRefReq pin. |
SYSREF_PULSE |
0: Continuous mode
1: Pulsed mode |
0 |
Continuous mode continuously makes SYSREF pulses, where pulsed mode makes a series of SYSREF_PULSE_CNT pulses. |
SYSREF_PULSE_CNT |
0 to 15 |
4 |
In the case of using pulsed mode, this is the number of pulses. Setting this to zero is an allowable, but not practical state. |
SYSREF_DIV |
0: Divide by 4
1: Divide by 6
2: Divide by 8
...
2047: Divide by 4098 |
0 |
This is one of the dividers between the VCO and SysRef output used in master mode. |
