7-0
Timing NCO Phase
Offset
These bits are used to offset the phase of the Timing NCO. The range is 0 to 1 times the resa-
mpler 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.
CONTROL WORD 14: TIMING FREQUENCY STROBE (SYNCHRONIZED TO PROCCLK)
BIT

FUNCTION
DESCRIPTION
N/A
Timing Frequency
Strobe
Writing to this address updates the active timing NCO Frequency Register in the timing NCO
(see Timing NCO Section).

DESCRIPTION
N/A
Timing Phase Strobe
Writing to this address updates the active timing NCO Phase Offset Register in the timing NCO
(see Timing NCO Section).

Re-Sampler Output
Pulse Delay
NOTE: These bits program the delay between output samples when interpolating. The extra out-
puts 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 out-
put 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.
0- Resampling Filter Enabled. A valid combination of bits 2-0 must also be selected.
1- Resampling Filter Section (including Interpolation halfband filters) is bypassed.
