Description
extended byte 1
determines VCO used during Normal
mode operations
enables AGC1 normal operation
whatever the tuner type, master or
slave.
determines which AGC will be updated
when detectors 1 and 2 are up
extended byte 2
extended byte 3
extended byte 4
forces the main PLL charge pump to
source current to the main PLL loop
filter
no force
extended byte 4
extended byte 5
extended byte 6
extended byte 7
forces the main PLL charge pump to
source current to the main PLL loop
filter
no force
extended byte 7
signal sensed by the power detector
used during calibrations
extended byte 8
extended byte 9
extended byte 10
calibration power detector output
LO VCO is used
CAL VCO is used
normal operation for the master;
6 dB fixed for the slave
normal operation for both the master
and the slave
