Signal Function
ROW10<0>
Control the synthesizer divider ratio and output frequency. Refer to Tables 9 and 10
for synthesizer control details.
ROW11<7:4>
Control the synthesizer divider ratio and output frequency. Refer to Tables 9 and 10
for synthesizer control details.
ROW11<3:1>
Control the VCO band, and must be changed when tuning the synthesizer output
frequency. Refer to Tables 9 and 10 for synthesizer control details.
These bits are for reserved for diagnostic purposes;
ROW11<0> = 1 for normal operation
These bits control the synthesizer charge pump bias.
ROW12<7:5> = 010 for normal operation
These bits control the width of the lock window for the synthesizer lock detector.
ROW12<4:1> = 1111 specifies the widest lock window for normal operation
This bit is for reserved for diagnostic purposes;
