Timing NCO Phase
Offset
These bits are used to offset the phase of the Timing NCO. The range is 0 to 1 times the resampler input
period interpreted either as
±
T/2(2’s complement) or 0 to T (offset binary). Bit 7 is the MSB. This location
is a holding register. After loading, a transfer to the Active Register is done by writing to Control Word 15
or by generating a SYNCIN2 with Control Word 11, Bit 5 set to 1.

Timing Phase Strobe
Writing to this address updates the active timing NCO Phase Offset Register in the timing NCO (see Tim-

Re-Sampler Output
Pulse Delay
NOTE: These bits program the delay between output samples when interpolating. The extra outputs can
be delayed from 2 to 255 clocks from the first output. A delay of 2 equals 255 clocks of delay. A
delay of 0 or 1 is an invalid mode. When interpolating by 2, one extra output is generated; when
interpolating by 4, 3 extra outputs are generated. Program by the equation (PROCCLK/f
OUT
) - 1.
Bit 11 is the MSB.
NOTE: If less than 5 is programmed, there will not be sufficient time to fully update the output
buffer. If less than 16 is programmed, the serial output may be preempted. This means that
it won’t finish and if the sync is programmed to follow the data, there may never be a sync.
