s PIN DESCRIPTIONS

( ) : for Bcc Package.

Pin No.

Pin Name

I/O

Descriptions

1 (16)

OSCIN

I

Programmable reference divider input.

Oscillator input connection to a TCXO.

2 (1)

OSCOUT

O

Oscillator output.

3 (2)

VP



Power supply voltage input for the charge pump.

4 (3)

VCC



Power supply voltage input.

5 (4)

DO

O

Charge pump output.

Phase of the charge pump can be reversed by FC input.

6 (5)

GND



Ground.

7 (6)

Xfin

I

Prescaler complementary input, and should be grounded via a capacitor.

8 (7)

fin

I

Prescaler input.

Connection with an external VCO should be done with AC coupling.

9 (8)

Clock

I

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.)

10 (9)

Data

I

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

counter.

Control bit

= “L” ; Data is transmitted to the programmable counter.

11 (10)

LE

I

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.

12 (11)

PS

I

Power saving mode control. This pin must be set at “L” at Power-ON.

(Open is prohibited.)

PS

= “H” ; Normal mode

PS

= “L” ; Power saving mode

13 (12)

ZC

I

Forced high-impedance control for the charge pump (with internal pull up

resistor.)

ZC

= “H” ; Normal Do output.

ZC

= “L” ; Do becomes high impedance.

14 (13)

LD/fout

O

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.)

15 (14)

φP

O

Phase comparator output for an external charge pump.

16 (15)

φR

O

Phase comparator output for an external charge pump.
