Phase Offset
These bits set the phase offset added (modulo 2
π
) to the phase output of the Cartesian to Polar
Converter. The phase offset is represented as a 4-bit fractional 2’s Complement value with the following
binary format:
Phase Offset = -2
0
. 2
-1
2
-2
2
-3.
This format provides a range from 0.875 to -1 (0111 to 1000) which corresponds to phase offset settings
from 7
π
/8 to -
π
respectively. Resolution of 22.5
o
is provided. Bit position 5 is the MSB.
1-0
Shift Factor
The bits set the left shift required by the Carrier Phase Error Detector. These two bits specify a left shift
of 0, 1, 2 or 3 places. MSBs are discarded and LSBs are zero-filled. Bit 1 is the MSB.

Discriminator Delay
The frequency detector (discriminator) computes frequency by subtracting a delayed phase term from
the current phase term (d
θ
/dt). A programmable delay is used to set the discriminator gain. These bits
set the delay as given by:
Delay = 2
K
,
where K is the 3-bit value programmed here. Delays of 1, 2, 4, 8, and 16 are possible.

DESCRIPTION

Frequency Offset
These bits set the frequency offset added (modulo) to the frequency output of the discriminator. The frequency
offset is represented as a 5-bit fractional 2’s complement value with the following binary format:
Frequency Offset = -2
0
. 2
-1
2
-2
2
-3
2
-4.
This format provides a range from 0.9375 to -1.0 (0111 to 1000). The range and resolution of the
frequency offset depend on the discriminator delay and input rate. The frequency offset is added to the
5 MSBs of the discriminator output. Note: Set the frequency offset to 0 when using frequency aided
acquisition with PSK waveforms.
2-0
Shift Factor
These bits set the left shift required by the Frequency Error Detector. These two bits set a left shift of 0,
1, 2, 3, or 4 places. Bit 2 is the MSB. Values greater than 4 are invalid.
Note: Set the shift factor to 0
when using frequency aided acquisition with PSK waveforms.

Lead/Lag to Serial
Output Routing
0 = The Carrier Loop Filter’s Lag Accumulator is routed to the Serial Output Controller.
1 = The lead and lag paths in the Carrier Loop Filter are summed and routed to the Serial Output
Controller.
