B-38
Group 4, APR 38–40 – set to 0x006D39.
The value for CAR_LF_INIT[23:0] is in accordance with
Equation B.52
Assuming an initial carrier frequency deviation of + .1 MHz is required,
the value for CAR_LF_INIT[23:0] is given as shown in
Equation B.53
Set Group 4, APR 40 to 0x00, APR 39 to 0x6D, and APR 38 to 0x39.
Group 4, APR 41 – Set to 0x65.
Set the bits in the Carrier Loop Configuration register as shown in
Table
Table B.9
If the carrier is locked but the constellation is rotated by 45 degrees,
reverse the polarity of bit 6 (
