fin
IF
I
Prescaler input pin for the IF-PLL.
Connection to an external VCO should be AC coupling.
4

Xfin
IF
I
Prescaler complimentary input pin for the IF-PLL section.
This pin should be grounded via a capacitor.
5

GND
IF
Ground pin for the IF-PLL section.
6

V
CCIF
Power supply voltage input pin for the IF-PLL section (except for the charge
pump circuit) , the shift register and the oscillator input buffer.
When power is OFF, latched data of IF-PLL is lost.

PS
IF
I
Power saving mode control signal pin for the IF-PLL section. This pin must be set
at “L” when the power supply is started up. (Open is prohibited.)
PS
IF
=
“H”; Normal mode / PS

IF
O
Charge pump output pin for the IF-PLL section.
Phase characteristics of the phase detector can be reversed by FC-bit.
10

LD/fout
O
Look detect signal output (LD) /phase comparator monitoring output (fout) pins.
The output signal is selected by an LDS bit in a serial data.
LDS bit
=
“H”; outputs fout signal / LDS bit
=
“L”; outputs LD signal
Charge pump output pin for the RF-PLL section.
Phase characteristics of the phase detector can be reversed by FC-bit.

LE
I
Load enable signal input pin (with the schmitt trigger circuit.)
On a rising edge of load enable, data in the shift register is transferred to the cor-
responding latch according to the control bit in a serial data.
19
17
Data
I
Serial data input pin (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.
20
18
Clock
I
Clock input pin 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.
