ICS557-01

PCI-EXPRESS CLOCK SOURCE

Description

Features

The ICS557-01 is a clock chip designed for use in

PCI-Express Cards as a clock source. It provides a pair

of differential outputs at 100 MHz in a small 8-pin SOIC

package.

• Supports PCI-Express HCSL Outputs

0.7 V current mode differential pair

• Supports LVDS Output Levels

• Packaged in 8-pin SOIC

Using ICS’ patented Phase-Locked Loop (PLL)

techniques, the device takes a 25 MHz crystal input

and produces HCSL (Host Clock Signal Level)

differential outputs at 100 MHz clock frequency. LVDS

signal levels can also be supported via an alternative

termination scheme.

• Available in Pb (lead) free package

• Operating voltage of 3.3 V

• Low power consumption

• Input frequency of 25 MHz

• Short term jitter 100 ps (peak-to-peak)

• Output Enable via pin selection

• Industrial temperature range available
