Description

DNC

2X

Do Not Connect.

OSCOFFSEL

1

I

4X

Set to “0” (GND) to turn off the oscillator when outputs are disabled (OE). Default (no connect) is

OSC always on.

GNDOSC

2

P

2X & 4X

GND connection for oscillator.

DNC

3

I

2X & 4X

Do Not Connect.

XIN

4

I

2X & 4X

Input from crystal oscillator circuitry.

XOUT

5

O

2X & 4X

Output from crystal oscillator circuitry.

OE

6

I

2X & 4X

Output Enable input. See “OE LOGIC SELECTION TABLE”.

DNC

2X

Do Not Connect.

L4X

7

I

4X

External inductor connection. The inductor is recommended to be a high Q small size 0402 or

0603 SMD component, and must be placed between L4X and adjacent VDDOSC. Place inductor

as close to the IC as possible to minimize parasitic effects and to maintain inductor Q. This

inductor is used with 4x AFMs.

GNDANA

2X

GND connection.

VDDOSC

8

P

4X

VDD connection for oscillator circuitry. VDDOSC should be separately decoupled from other

VDDs whenever possible.

GNDBUF

9

P

2X & 4X

GND connection.

Q

10

O

2X & 4X

PECL/LVDS/CMOS output.

QBAR

11

O

2X & 4X

Complementary PECL/LVDS output or in-phase CMOS.

VDDBUF

12

P

2X & 4X

VDD connection for output buffer circuitry. VDDBUF should be separately decoupled from other

VDDs whenever possible.

13

2X

OESEL

14

I

4X

Selector input to choose the OE control logic (see “OE SELECTION TABLE”). If no connection

is applied, value will be set to default through internal pull-down resistor.

14

2X

VDDANA

13

P

4X

VDD connection for analog circuitry.VDDANA should be separately decoupled from other VDDs

whenever possible.

VDDOSC

15

P

2X & 4X

VDD connection for oscillator. VDD should be separately decoupled from other VDDs whenever

possible.

L2X

16

I

2X & 4X

External inductor connection. The inductor is recommended to be a high Q small size 0402 or

0603 SMD component, and must be placed between L2X and adjacent VDDOSC. Place inductor

as close to the IC as possible to minimize parasitic effects and to maintain inductor Q.

Note: 663-xx devices are 2x multipliers, and 660-xx devices are 4x multipliers.
