Timing NCO Phase
Accumulator Load
On Update
When this bit is set to 1, the
μ
P update to the timing NCO frequency or an external timing NCO
load using SYNCIN2 will zero the feedback of the phase accumulator as well as update the
phase and frequency. This function can be used to set the NCO to a known phase synchronized
to an external event.

DESCRIPTION
31-0
Timing NCO Center
Frequency
These bits control the frequency of the timing NCO. The frequency range of the NCO is from 0
to F
RESAMP
where F
RESAMP
is the input sample rate to the re-sampling filter. The bits are com-
puted by the equation: N =(f

. Bit 31 is the MSB. This location is a holding
register. After loading, a transfer to the active register is done by writing to Control Word 14 or
by generating a SYNCIN2 with Control Word 11 bit 5 set to 1.

7-0
Timing NCO Phase
Offset
These bits are used to offset the phase of the carrier 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.

FUNCTION
DESCRIPTION
N/A

Writing to this address updates the active timing NCO frequency register in the timing NCO (see
Timing NCO Section).
CONTROL WORD 15: TIMING PHASE STROBE (SYNCHRONIZED TO PROCCLK)
BIT

FUNCTION
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).
