2.10 Receive VHF PLL Reference Divider Programming Register - Address 12
Bits 23:19 are unused and should be set to '0'
Bit 18 selects common reference divider for VHF receive and transmit PLLs ('0' to select). If a common reference
divider is selected then the transmit VHF reference divider is used which must be programmed in register 13.
Bits 17:4 set the Reference divider value (Bit 17 = MSB)
2.11 Transmit VHF PLL Divider Programming Register - Address 13
Bits 23:21 are unused and should be set to '0'
Bits 20:8 set M counter value (Bit 20 = MSB)
Bits 7:4 set A counter value - max value = 15 (Bit 7 = MSB)
Programming is identical to that for the receive VHF PLL register 11.
2.12 Transmit VHF PLL Reference Divider Programming Register Address 14
Bits 23:18 are unused and should be set to '0'
Bits 17:4 set the Reference counter value (Bit 17 = MSB)
2.13 PLL Lock Detect & Fractional N Compensation Programming Register Address 15
2.13.1 Fractional N Compensation
Bits 23:16 set the value for fractional N compensation in the UHF PLL with bit 23 as MSB. The value for the
compensation is dependent on a number of parameters which are described in the synthesizer section.
