Function

Input for the VCO frequency.

Ground to 0 V.

Power supply voltage terminal. 5.0 V ± 0.5 V

Power supply for band switching, VCC1 to 13.2 V

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 (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 35 V

A/D conversion of the input voltage.

In control byte data input, the programmable 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, it outputs lock detector output and power down flag

and a state of 5 level A/D converter.

Chip address sets it up with the input condition of terminal.

4.0 MHz crystal oscillator is connected.
