BIT
POSITION
FUNCTION
DESCRIPTION
0
HI/LO Output Sense
1 = HI/LO output of 1 means input > threshold.
0 = HI/LO output of 1 means input
≤
threshold.
(See Input Level Detector Section).
1
AGC Disable
1 = AGC disabled, gain forced to 1.0 (0dB), 0 = Normal operation.
(See AGC Section).
2
AGC Level Detector
Sense
1 = Error signal is 1 when output > threshold, -1 otherwise.
0 = Error signal is -1 when output > threshold, 1 otherwise.
Set to 0 for normal operation. (See AGC Section).
4-3
Carrier Offset
Frequency Word Width
0 0 = 8 bits
0 1 = 16 bits
1 0 = 24 bits
1 1 = 32 bits
(See Synthesizer/Mixer Section).
6-5
Sample Rate Offset
Frequency Word Width
0 0 = 8 bits
0 1 = 16 bits
1 0 = 24 bits
1 1 = 32 bits
(See Re-Sampler Section).
7
Carrier Offset
Frequency Enable
1 = Enable Offset Frequency, 0 = Zero Offset Frequency.
(See Synthesizer/Mixer Section).
8
Sample Rate Offset
Frequency Enable
1 = Enable Offset Frequency, 0 = Zero Offset Frequency.
(See Re-Sampler Section).
9
Load Synthesizer NCO
1 = Accumulation enabled.
0 = Feedback in accumulator is zeroed.
(See Synthesizer/Mixer Section) Set to 1 for normal operation.
10
Load Re-Sampler NCO
1 = Accumulation enabled.
0 = Feedback in accumulator is zeroed.
(See Re-Sampler Section) Set to 1 for normal operation.
12-11
Sample Phase Output
Select
Selects 5 of the 8 MSBs of the Re-Sampler NCO’s phase accumulator for output on SPH0-4. (See Re-
Sampler Section).
0 0 Bits 28:24.
0 1 Bits 29:25.
1 0 Bits 30:26.
1 1 Bits 31:27.
13
Sample Phase
Output Control
Selects whether the sample phase output pins and SSTRB update continuously or only when the DA-
TARDY is active. (See Re-Sampler Section).
1 = Continuous Update.
0 = Updated by DATARDY.
14
Clear Accumulators
Writing a 1 to the Clear Accumulator bit forces the contents of all accumulators to 0. Accumulators will
remain at 0 until a 0 is written to this bit. The following accumulators are affected by this bit.
Carrier NCO Accumulator
Cascode CIC Filter Accumulator
AGC Loop Filter Accumulator
Serial Output Shifter Counter
Serial Output Clock Logic
ReSampler NCO Carry Output Programmable Divider
