ICS844011I

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO- LVDS

CLOCK GENERATOR

GENERAL DESCRIPTION

FEATURES

• (1) Differential LVDS output

The ICS844011I is a Fibre Channel Clock

ICS

Generator and a member of the HiPerClocks^TM

family of high performance devices from ICS.

The ICS844011I uses an 18pF parallel resonant

crystal over the range of 20.4MHz - 28.3MHz. For

HiPerClockS™

• Crystal oscillator interface, 18pF parallel resonant crystal

(20.4MHz - 28.3MHz)

• Output frequency range: 81.66MHz - 113.33MHz

• VCO range: 490MHz - 680MHz

Fibre Channel applications, a 26.5625MHz crystal is used.

The ICS844011I has excellent <1ps phase jitter per-

formance, over the 637kHz - 10MHz integration range. The

ICS844011I is packaged in a small 8-pin TSSOP, making it

ideal for use in systems with limited board space.

• RMS phase jitter @ 106.25MHz, using a 26.5625MHz crystal

(637kHz - 10MHz): 0.75ps (typical)

• 3.3V or 2.5V operating supply

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