Ground for RX–PLL section.
The programmable reference divider input. TCXO should be connected with a
AC coupling capacitor.
Ground for the TX-PLL section.
Prescaler input pin for the TX-PLL.
The connection with VCO should be AC coupling.
Power supply voltage input pin for the TX-PLL section.
When power is OFF, latched data of TX-PLL is cancelled.
Prescaler complimentary input for the TX-PLL section.
This pin should be grounded via a capacitor.

Charge pump output for the TX-PLL section.
Phase characteristics of the phase detector can be reversed by FC-bit.
Analog switch output for the TX selection.
Ground 2 for the RX section.
Charge pump output for the RX-PLL section.
Phase characteristics of the phase detector can be reversed by FC-bit.

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
Prescaler complimentary input for the RX-PLL section.
This pin should be grounded via a capacitor.
Power supply voltage input pin for the RX-PLL section.
When power is OFF, latched data of RX-PLL is cancelled.
Prescaler input pin for the RX-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 (TX-ref counter, TX-Prog.
counter, RX-ref. counter, RX-prog. counter) according to the control bit in a
