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 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.
This supplies the tuning voltage.
Power supply voltage for tuning voltage 28 to 35V
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.
Data is read into the shift register when the clock signal falls.
Input for band SW and programmable freq. divider set up.
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.
4.0MHz crystal oscillator is connected.
