CLOCKS™LVCMOS/CRYSTAL- -

3.3V LVPECL FREQUENCY

SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS843004 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,

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 ICS843004 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 ICS843004 is packaged in a small 24-pinTSSOP package.

• VCO range: 560MHz - 680MHz

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

(637KHz - 10MHz): 0.72ps (typical)

• RMS phase noise at 212.5MHz (typical)

Phase noise:

Offset

Noise Power

100Hz ............... -95.0 dBc/Hz

1KHz ..............-114.3 dBc/Hz

10KHz ..............-123.8 dBc/Hz

100KHz ..............-124.6 dBc/Hz

• Full 3.3V supply mode

• -30°C to 85°C ambient operating temperature
