PRELIMINARY

ICS843252-04

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO-

3.3V LVPECL CLOCK GENERATOR

GENERAL DESCRIPTION

FEATURES

• Two differential 3.3V LVPECL output

The ICS843252-04 is a 10Gb/12Gb Ethernet

ICS

HiPerClockS™

Clock Generator and a member of the

HiPerClocks^TMfamily of high performance

devices from ICS. The ICS843252-04 can

synthesize 10 Gigabit Ethernet and 12 Gigabit

• Crystal oscillator interface designed for

18pF parallel resonant crystals

• Crystal input frequency range: 19.33MHz - 30MHz

• Output frequency range: 145MHz - 187.5MHz

• VCO frequency range: 580MHz - 750MHz

Ethernet with a 25MHz crystal. It can also generate SATA

and 10Gb Fibre Channel reference clock frequencies with

the appropriate choice of crystals. The ICS843252-04 has

excellent phase jitter performance and is packaged in a

small 16-pin TSSOP, making it ideal for use in systems with

limited board space.

• RMS phase jitter at 156.25MHz (1.875MHz - 20MHz):

0.39ps (typical)

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request

• Available in both standard and lead-free compliant

packages
