PRELIMINARY

FEMTOCLOCKS™ 680MHZ, CRYSTAL-TO-3.3V

DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER

ICS843202I

GENERAL DESCRIPTION

FEATURES

The ICS843202I is a 2 output LVPECL Synthesizer

• Two 3.3V LVPECL outputs

ICS

HiPerClockS™

optimized to generate Gigabit Ethernet and SONET

reference clock fre-quencies and is a member of

the HiPerClocks^TMfamily of high performance clock

solutions from ICS. Using a 19.44MHz and 25MHz,

• Selectable crystal oscillator interface

or one differential recovered clock inputs

• Supports the following output frequencies: 155.52MHz

and 156.25MHz

18pF parallel resonant crystal, 155.52MHz and 156.25MHz

frequencies can be generated. The part also allows the use of

a recovered clock at QB output. The ICS843202I uses ICS’

FemtoClock^TMlow phase noise VCO technology and can achieve

1ps or lower typical RMS phase jitter. The ICS843202I is

packaged in a 32-pin LQFP 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 25MHz crystal

(1.875MHz - 20MHz): 0.56ps (typical)
