FEMTOCLOCKS™ CRYSTAL-TO-

3.3V LVPECL FREQUENCY SYNTHESIZER

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS843002-01 is a 2 output LVPECL • Two 3.3V LVPECL outputs

ICS

synthesizer optimized to generate Ethernet

reference clock frequencies and is a member of

the HiPerClocks^TMfamily of high performance

clock solutions from ICS. Using a 25MHz 18pF

• Selectable crystal oscillator interface

or LVCMOS single-ended input

HiPerClockS™

• Supports the following input frequencies:

156.25MHz, 125MHz and 62.5MHz

parallel resonant crystal, the following frequencies can be

generated based on the 2 frequency select pins

(F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz. The

ICS843002-01 uses ICS’3^rdgeneration low phase noise VCO

technology and can achieve 1ps or lower typical rms phase

jitter, easily meeting Ethernet jitter requirements. The

ICS843002-01 is packaged in a small 20-pinTSSOP package.

• VCO range: 560MHz - 680MHz

• RMS phase jitter @ 156.25MHz, using a 25MHz crystal

(1.875MHz-20MHz): 0.54ps (typical)

• Typical phase noise at 156.25MHz

Phase noise:

Offset

Noise Power

100Hz ............... -97.3 dBc/Hz

1KHz ..............-119.1 dBc/Hz

10KHz ..............-126.4 dBc/Hz

100KHz ..............-127.6 dBc/Hz

• Full 3.3V supply mode

• Lead-Free package fully RoHS compliant

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