Programmable reference divider input.
Oscillator input.
Connection for an crystal or a TCXO.
TCXO should be connected with a coupling capacitor.
Oscillator output.
Connection for an external crystal.
Power supply voltage input for the charge pump.
Power supply voltage input.
Charge pump output.
Phase of the charge pump can be reversed by FC input.
Ground.
Prescaler complementary input, and should be grounded via a capacitor.
Prescaler input.
Connection with an external VCO should be done with AC coupling.
Clock input for the 19-bit shift register.
Data is shifted into the shift register on the rising edge of the clock. (Open
is prohibited.)
Serial data input using binary code.
The last bit of the data is a control bit. (Open is prohibited.)
Control bit = ”H” ; Data is transmitted to the programmable reference
Control bit = ”L” ; Data is transmitted to the programmable counter.
Load enable signal input (Open is prohibited.)
When LE is high, the data in the shift register is transferred to a latch,
according to the control bit in the serial data.
Power saving control input. This pin should be set at ”L” at Power-ON.
(Open is prohibited.)
PS = ”H” ; Normal mode
PS = ”L” ; Power saving mode
Forced high-impedance control for the charge pump (with internal pull up
resistor.)
ZC = ”H” ; Normal Do output.
ZC = ”L” ; Do becomes high impedance.
Lock detect signal output(LD)/ phase comparator monitoring
output (fout).
The output signal is selected by LDS bit in the serial data.
LDS = ”H” ; outputs fout (fr/fp monitoring output)
LDS = ”L” ; outputs LD (”H” at locking, ”L” at unlocking.)
Phase comparator output for an external charge pump.
Phase comparator output for an external charge pump.
counter.
