ICS844051-11

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ CRYSTAL-TO- LVDS

CLOCK GENERATOR

GENERAL DESCRIPTION

FEATURES

The ICS844051-11 is a Gigabit Ethernet • (1) Differential LVDS output

ICS

Generator and a member of the HiPerClocks^TM

family of high performance devices from ICS.

The ICS844051-11 can synthesize 10 Gigabit

Ethernet, SONET, or Serial ATA reference

• Crystal oscillator interface designed for

18pF parallel resonant crystals

HiPerClockS™

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

0.45ps (typical)

clock frequencies with the appropriate choice of crystal

and output divider. The ICS844051-11 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.

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
