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 (f1/N) is ahead compared to the refer-

ence 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.

Power supply voltage 3

Power supply voltage for tuning voltage 28 to 35V

12

LD/ftest

Lock detect/Test port

When 18/19 bit data is input, lock detector is output.

When 27 bit data is input, lock detector is output, the programmable freq.

Divider output and reference freq.

Output is selected by the test mode.

13

CLK

Clock input

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

14

DATA

Data input

Input for band SW and programmable freq. divider set up.

15

ENA

Enable input

This is normally at a "L". When this is at "H", data and clock signals are received.

Data is read into the latch when the enable signal after the 18th signal of the clock

signal falls or when the 19th pulse of the clock signal falls.
