DESCRIPTION
N/A
Sample AGC Gain
Level
Writing to this location samples the output of the AGC loop filter to stabilize the value for
μ
P reading.

5
Enable External
Timing NCO Sync
0- SYNCIN2 has no effect on the timing NCO.
1- When SYNCIN2 is asserted, the timing NCO center frequency and phase are updated with the value
loaded in their holding registers. If bit 0 of this word is set to 1, the phase accumulator feedback is also
zeroed.
4-3
Number of Offset Fre-
quency Bits
00 - 8 bits.
01 - 16.
10 - 24.
11 - 32.

Frequency
0- Zero Offset Frequency to Adder.
1- Enable Offset Frequency.

0- Enable Accumulator.
1- Zero Feedback in Accumulator.

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 fre-
quency. This function can be used to set the NCO to a known phase synchronized to an external event.
CONTROL WORD 12: TIMING NCO CENTER FREQUENCY (SYNCHRONIZED TO PROCCLK)
BIT
POSITION
FUNCTION
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
RE-
SAMP
where F
RESAMP
is the input sample rate to the resampling filter. The bits are computed 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.
