PRELIMINARY

ICS840245I

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ 1:5, CRYSTAL-TO-

LVCMOS/LVTTL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

• Five LVCMOS outputs, 15Ω typical output impedance

• Crystal oscillator interface

The ICS840245I is a low skew, 1-to-5 LVCMOS/

ICS

LVTTL SATA/SAS Clock Generator and is a

member of the HiPerClocks^TMfamily of high

performance clock solutions from ICS. The

ICS840245I can synthesize 75MHz reference

HiPerClockS™

• Supports the following output frequency: 75MHz

• Output skew: 45ps (typical)

clock frequencies with a 25MHz crystal. Each of the 5 outputs

on the ICS840245I can drive two series terminated 50Ω

transmission lines, effectively making the ICS840245I a 1-to-10

clock generator. An output enable (OE) pin, which controls

only the Q4 output, allows the application to use Q4 as an

optional output (for example, test output pin).The ICS840245I

uses ICS’ 3^rdgeneration low phase noise VCO technology

and can achieve 1ps or lower typical random rms phase

jitter.The ICS840245I is packaged in a 16-pin TSSOP package.

• RMS phase jitter @ 75MHz (900kHz - 7.5MHz):

0.454ps (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

• Available in both standard and lead-free RoHS compliant

packages
