Function
Input for the VCO frequency.
Ground to 0V.
Power supply voltage terminal. 5.0V±0.5V
Power supply for band switching, Vcc1 to 13.2V
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.
This is the output terminal for the LPF input and charge pump output.
When the phase of the programmable divider output (f1/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
Lock detector is output.
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.
Chip address sets it up with the input condition of terminal.
4.0MHz crystal oscillator is connected.
