PCI-EXPRESS CLOCK SOURCE

Description

The ICS557-03 is a spread spectrum clock generator

supporting PCI-Express and Ethernet requirements.

The device is used for PC or embedded systems to

substantially reduce electromagnetic interference

(EMI). The device provides two differential (HCSL)

spread spectrum outputs. This device is pin configured

to select spread and clock selection. Using ICS’

patented Phase-Locked Loop (PLL) techniques, the

device takes a 25 MHz crystal input and produces two

pairs of differential outputs (HCSL) at 25 MHz, 100

MHz, 125 MHz and 200 MHz clock frequencies. It also

provides spread selection of ±0.25%, -0.5%, -0.75%,

and no spread.

Features

• Packaged in 16-pin TSSOP

• Available in Pb (lead) free package

• Supports LVDS Output Levels

• Operating voltage of 3.3 V

• Input frequency of 25 MHz

• Outputs (HCSL, 0.7 V Current mode differential pair)

• Jitter 100 ps (peak-to-peak)

• Spread of ±0.25%, -0.5%, -0.75%, and no spread.

• Industrial and commercial temperature ranges
