PRELIMINARY

ICS8422002I

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ CRYSTAL-TO-

LVHSTL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS8422002I is a 2 output LVHSTL • Two LVHSTL outputs (VOHmax = 1.2V)

ICS

HiPerClockS™

Synthesizer optimized to generate Fibre

• Selectable crystal oscillator interface

Channel reference clock frequencies and is a

or LVCMOS/LVTTL single-ended input

member of the HiPerClocks^TMfamily of high

performance clock solutions from ICS. Using

• Supports the following output frequencies: 212.5MHz,

187.5MHz, 159.375MHz, 106.25MHz, 53.125MHz

a 26.5625MHz 18pF parallel resonant crystal, the following

frequencies can be generated based on the 2 frequency

select pins (F_SEL[1:0]): 212.5MHz, 187.5MHz,

159.375MHz, 106.25MHz and 53.125MHz. The

ICS8422002I uses ICS’ 3^rdgeneration low phase noise

VCO technology and can achieve 1ps or lower typical rms

phase jitter, easily meeting Fibre Channel jitter

requirements. The ICS8422002I is packaged in a 20-pin

TSSOP package.

• VCO range: 560MHz - 680MHz

• RMS phase jitter @ 212.5MHz, using a 26.5625MHz crystal

(637kHz - 10MHz): 0.59ps (typical)

• Power supply modes:

Core/Output

3.3V/1.8V

2.5V/1.8V

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

• Available in both standard and lead-free RoHS-compliant

packages
