Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO- LVDS

CLOCK GENERATOR

GENERAL DESCRIPTION

FEATURES

• (1) Differential LVDS output

The ICS844031I-01 is an Ethernet Clock

ICS

Generator and a member of the HiPerClocks^TM

family of high performance devices from ICS.The

ICS844031I-01 uses an 18pF parallel resonant

crystal over the range of 19.6MHz - 27.2MHz. For

HiPerClockS™

• Crystal oscillator interface, 18pF parallel resonant crystal

(19.6MHz - 27.2MHz)

• Output frequency range: 245MHz - 340MHz

• VCO range: 490MHz - 680MHz

Ethernet applications, a 25MHz crystal is used to generate

312.5MHz.The ICS844031I-01 has excellent <1ps phase jitter

performance, over the 1.875MHz - 20MHz integration range.

The ICS844031I-01 is packaged in a small 8-pin TSSOP,

making it ideal for use in systems with limited board space.

• RMS phase jitter @ 312.5MHz, using a 25MHz crystal

(1.875MHz - 20MHz): 0.49ps (typical)

• 3.3V or 2.5V operating supply

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