OSCIN

I

Programmable reference divider 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 selected via programming of the FC bit.

 

 

 

 

 

 

 

 

 

6

5

GND

Ground.

 

 

 

 

 

7

6

Xfin

I

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

 

 

 

 

 

8

7

fin

I

Prescaler input.

Connection to an external VCO should be done via AC coupling.

 

 

 

 

 

 

 

 

 

 

 

 

 

Clock input for the 19-bit shift register.

9

8

Clock

I

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.)

 

 

 

 

 

 

 

 

 

 

 

 

 

Load enable signal input. (Open is prohibited.)

11

10

LE

I

When LE is set high, the data in the shift register is transferred to a latch

 

 

 

 

according to the control bit in the serial data.

 

 

 

 

 

 

 

 

 

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

12

11

PS

I

(Open is prohibited.)

PS = “H”; Normal mode

 

 

 

 

 

 

 

 

PS = “L”; Power saving mode

 

 

 

 

 

 

 

 

 

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

13

12

ZC

I

resistor.)

ZC = “H”; Normal Do output.

 

 

 

 

 

 

 

 

ZC = “L”; Do becomes high impedance.

 

 

 

 

 

 

 

 

 

Lock detect signal output (LD)/phase comparator monitoring output (fout).

14

13

LD/fout

O

The output signal is selected via programming of the LDS bit.

LDS = “H”; outputs fout (fr/fp monitoring output)

 

 

 

 

 

 

 

 

LDS = “L”; outputs LD (“H” at locking, “L” at unlocking.)

 

 

 

 

 

15

14

φP

O

Phase comparator N-channel open drain output for an external charge

pump. Phase can be selected via programming of the FC bit.

 

 

 

 

 

 

 

 

 

16

15

φR

O

Phase comparator CMOS output for an external charge pump. Phase can

be selected via programming of the FC bit.
