PRELIMINARY

ICS8422004I

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™LVCMOS/CRYSTAL-TO-

LVHSTL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS8422004I is a 4 output LVHSTL Synthesizer • Four LVHSTL outputs (VOHmax = 1.2V)

ICS

HiPerClockS™

optimized to generate Fibre Channel reference

clock frequencies and is a member of the

HiPerClocks^TMfamily of high performance clock

solutions from ICS. Using a 26.5625MHz 18pF

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

• Supports the following output frequencies: 212.5MHz,

187.5MHz, 159.375MHz, 156.25, 106.25MHz, 53.125MHz

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, 156.25, 106.25MHz and

53.125MHz. The ICS8422004I 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 ICS8422004I is packaged in a small

24-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
