ICS840008-01

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ CRYSTAL-TO-LVCMOS/LVTTL

FREQUENCY SYNTHESIZER

FEATURES

GENERAL DESCRIPTION

• Eight LVCMOS/LVTTL outputs, 15Ω typical output impedance

• Output frequency range: 125MHz - 160MHz

• Crystal oscillator interface, 25MHz - 32MHz crystal

• VCO range: 500MHz - 640MHz

The ICS840008-01 is an 8 output LVCMOS/LVTTL

ICS

Synthesizer designed to generate 125MHz for

Gigabit Ethernet applications and is a member of

the HiPerClocks^TMfamily of high performance clock

solutions from ICS.The ICS840008-01 uses ICS’

HiPerClockS™

3rd generation low phase noiseVCO technology and can achieve

1ps or lower typical random rms phase jitter, easily meeting

Gigabit Ethernet jitter requirements. The ICS840008-01 is

packaged in a small 24-pin SSOP package.

• RMS phase jitter (1.875MHz - 20MHz): 0.52ps (typical)

• Output skew: 150ps (maximum) (design target)

• Voltages supply modes:

2.5V/1.8V

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
