Oscillator input pin.
Oscillator output pin.
A crystal is connected between OSC
Prescaler input pin of transmit section.
The connection with VCO should be AC connection.
Power supply voltage input pin of transmit section.
When power is OFF, latched data of transmit section is cancelled.
Monitor pin for programmable reference divider output.
Lock detect signal output pin of transmit section.
Power supply voltage input for charge pump and analog switch of transmit section.
Charge pump output pin of transmit section.
Phase characteristics of the phase detector can be reversed depending upon FC-bit setting.
Analog switch output pin of transmit section.
Usually this pin is high-impedance state. During SW is ON (LE = high), charge pump output is con-
nected to this pin.
Analog switch output pin of reception section.
Usually this pin is high-impedance state. During SW is ON (LE = high), charge pump output is con-
nected to this pin.
Charge pump output pin of reception section.
Phase characteristics of the phase detector can be reversed depending upon FC-bit setting.
Power supply voltage input for charge pump and analog switch of reception section.
Lock detect signal output pin of reception section.
Monitor pin for programmable divider output.
This pin outputs divided frequency of transmit section or reception section depending upon FP bit set-
ting.
