PRELIMINARY

ICS843204I

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ CRYSTAL-TO-

3.3V LVPECL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS843204I is a 4 output LVPECL

• Four 3.3V LVPECL outputs

ICS

HiPerClockS™

Synthesizer optimized to generate Gigabit

Ethernet and SONET reference clock fre-

quencies and is a member of the HiPerClocks^TM

family of high performance clock solutions from

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

• Supports the following output frequencies: 155.52MHz

and 156.25MHz

ICS. Using a 19.44MHz and 25MHz, 18pF parallel resonant

crystal, 155.52MHz and 156.25MHz frequencies can be

generated. The ICS843204I uses ICS’ FemtoClock^TMlow

phase noise VCO technology and can achieve 1ps or lower

typical RMS phase jitter. The ICS843204I is packaged in a

48-pin TSSOP package.

• VCO range: 560MHz - 680MHz

• RMS phase jitter @ 155.52MHz, using a 19.44MHz crystal

(12kHz - 13MHz): 0.86ps (typical)

• RMS phase jitter @ 156.25MHz, using a 19.44MHz crystal

(1.875MHz - 20MHz): 0.52ps (typical)

• Full 3.3V supply mode

• -40°C to 85°C ambient operating temperature

• Available in both standard and lead-free RoHS

compliant packages
