Pin number

Function

Description

1

ScK

Serial port clock input

2

SDi

Serial port data input

3

DVDD

Power supply pin for internal digital circuitry. nominally 3V

4

VDDio

Power Supply for digital i/o driver

5

LD_SDo

Lock Detect, Main Serial Data output

or Vco Serial Port Data out

6

D0

GPo output Bit 0, Vco Serial Port LE

when in Vco Serial Port Mode

7

D1

GPo output Bit 1, Vco Serial Port clock

when in Vco Serial Port Mode

8

DVDDM

Digital Power Supply for M-counter, nominally 3V

9

VccPS

analog Power Supply for Prescaler, nominally 3V

10

rFiP

input to the rF Prescaler. this small signal

input is ac-coupled to the external Vco.

11

rFin

complementary input to the rF Prescaler. For single-ended input

this point must be decoupled to the ground plane with a ceramic

bypass capacitor, typically 100 pF.

12

aVcc

analog Power supply pin for the rF Section.

a decoupling capacitor to the ground plane should

be placed as close as possible to this pin. nominally 3V

13

VDDcP

+5V Power Supply for charge pump digital section

14

VcccP

+5V Power Supply for the charge pump analog section

15

cP

charge pump output

16

VDDPFD

analog Power supply for the phase frequency detector, nominally 3V

17

18

aVDD

analog Power supply for analog ref paths, nominally 3V

19

rEFn

reference input (negative or decoupled)

20

rEFP

reference input (Positive)

21

rVDD

ref path supply

22

DVDDQ

Digital supply for Substrate, nominally 3V

23

cE

chip Enable

24

SEn

Serial port latch enable input

[1] notE: BiaS ref voltage cannot drive an external load. Must be measured with 10Gohm meter such as agilent 34410a, typical 10Mohm DVM

will read erroneously.
