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.

9

Vin

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.

Vtu

Tuning output

This supplies the tuning voltage.

11

Power supply voltage 3

Power supply voltage for tuning voltage 28 to 35V

12

ADC/ftest

AD converter input/

Test port

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.

13

SCL

Clock input

Data is read into the shift register when the clock signal falls.

14

SDA

Data input

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.

15

ADS

Address switching input

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

This is connected to the

crystal oscillator

4.0MHz crystal oscillator is connected.
