LOCKS™ CRYSTAL

3.3V LVPECL CLOCK

GENERATOR

GENERAL DESCRIPTION

FEATURES

The ICS843031 is a 1 Gigabit Ethernet Clock • 1 differential 3.3V LVPECL output

ICS

Generator and a member of the HiPerClocks^TM

• Crystal oscillator interface designed for

family of high performance devices from ICS.The

18pF parallel resonant crystals

HiPerClockS™

ICS843031 can synthesize 1 Gigabit Ethernet,

SONET, or Serial ATA reference clock frequencies

• VCO frequency range: 580MHz - 700MHz

with the appropriate choice of crystal and output divider. The

ICS843031 has excellent phase jitter performance and is

packaged in a small 8-pin TSSOP, making it ideal for use in

systems with limited board space.

• RMS phase jitter @312.5MHz (1.875MHz - 20MHz):

0.5ps (typical)

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
