PRELIMINARY

ICS840004I-01

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ CRYSTAL-TO-

LVCMOS/LVTTL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

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

The ICS840004I-01 is a 4 output LVCMOS/LVTTL

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 output frequencies:

156.25MHz, 125MHz and 62.5MHz

parallel resonant crystal, the following frequencies can be

generated based on the 2 frequency select pins (F_SEL1:0):

156.25MHz, 125MHz, and 62.5MHz.The ICS840004I-01 uses

ICS’ 3^rdgeneration low phase noise VCO technology and can

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

meeting Ethernet jitter requirements. The ICS840004I-01 is

packaged in a small 20-pin TSSOP package.

• RMS phase jitter @ 156.25MHZ (1.875MHz - 20MHz):

0.52ps (typical)

• Output supply modes:

Core/Output

3.3V/3.3V

3.3V/2.5V

2.5V/2.5V

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