Ground for RF-PLL section.
The programmable reference divider input. TCXO should be connected
with a AC coupling capacitor.
Ground for the IF-PLL section.
Prescaler input pin for the IF-PLL.
The connection with VCO should be AC coupling.
Power supply voltage input pin for the IF-PLL section.
Lock detect signal output (LD) / phase comparator monitoring output (fout)
The output signal is selected by a LDS bit in a serial data.
LDS bit = “H” ; outputs fout signal
LDS bit = “L” ; outputs LD signal
Power saving mode control for the IF-PLL section. This pin must be set
at “L” Power-ON. (Open is prohibited.)

Charge pump output for the IF-PLL section.
Phase characteristics of the phase detector can be reversed by FC-bit.
Charge pump output for the RF-PLL section.
Phase characteristics of the phase detector can be reversed by FC-bit.
Power saving mode control for the RF-PLL section. This pin must be set
at “L” Power-ON. (Open is prohibited.)

Prescaler complimentary input for the RF-PLL section.
This pin should be grounded via a capacitor.
Power supply voltage input pin for the RF-PLL section, the shift register and
the oscillator input buffer. When power is OFF, latched data of RF-PLL is
cancelled.
Prescaler input pin for the RF-PLL.
The connection with VCO should be AC coupling.
Load enable signal input (with the schmitt trigger circuit.)
When LE is “H”, data in the shift register is transferred to the corresponding
Serial data input (with the schmitt trigger circuit.)
A data is transferred to the corresponding latch (IF-ref counter, IF-prog.
counter, RF-ref. counter, RF-prog. counter) according to the control bit in a
serial data.
Clock input for the 23-bit shift register (with the schmitt trigger circuit.)
One bit data is shifted into the shift register on a rising edge of the clock.
latch according to the control bit in a serial data.
