Band switching outputs
PNP open collector method is used.
When the band switching data is "H", the output is ON.
When it is "L", the output is OFF.

Filter input
(Charge pump output)
This is the output terminal for the LPF input and charge pump output. When the
phase of the programmable divider output (f 1/N) is ahead compared to the
reference frequency (fref), the "source" current state becomes active.
If it is behind, the "sink" current becomes active.
If the phases are the same, the high impedance state becomes active.
This supplies the tuning voltage.
Power supply voltage for tuning voltage 28 to 35V
A/D conversion of the input voltage.
In control byte data input, the programmabule freq. Divider output and reference
freq. output is selected by the test mode.
Data is read into the shift register when the clock signal falls.
Input for band SW and programmable freq. divider set up.
In lead mode, itoutputs lock detector output and power down flagand a state of 5
level A/D converter.
Chip address sets it up with the input condition of terminal.
