ICS843002

FEMTOCLOCKS™ CRYSTAL-TO-

3.3V LVPECL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

The ICS843002 is a 2 output LVPECL synthesizer

optimized to generate Fibre Channel reference

clock frequencies and is a member of the

HiPerClocksTM family of high performance clock

solutions from ICS. Using 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 ICS843002 uses ICS’ 3rd generation low

phase noise VCO technology and can achieve 1ps or lower

typical rms phase jitter, easily meeting Fibre Channel jitter

requirements. The ICS843002 is packaged in a small 20-pin

TSSOP package.

FEATURES

• Two 3.3V LVPECL outputs

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

• Supports the following output frequencies: 212.5MHz,

187.5MHz, 159.375MHz, 106.25MHz and 53.125MHz

• VCO range: 560MHz - 680MHz

• RMS phase jitter (637kHz - 10MHz): 0.72ps (typical)

• Typical phase noise at 212.5MHz

Phase noise:
