CLOCKS™ CRYSTAL- -

3.3V, 2.5V LVPECL FREQUENCY

SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS843004I is a 4 output LVPECL synthesizer • Four 3.3V LVPECL outputs

ICS

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

HiPerClockS™

• Supports the following output frequencies: 212.5MHz,

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, 156.25MHz, 106.25MHz,

and 53.125MHz.The ICS843004I 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 ICS843004I is packaged in a small 24-pin

TSSOP package.

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

• VCO range: 560MHz - 680MHz

• Output skew: 50ps (maximum)

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

(2.55MHz - 20MHz): 0.47ps (typical)

• Full 3.3V or 2.5V supply modes

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

• Lead-Free fully RoHS compliant
