PCI Express

Clock Generator

ICS841S04I

DATA SHEET

General Description

The ICS841S04I is a PLL-based clock generator specifically

designed for PCI_Express™ Clock Generation applications. This

device generates a 100MHz HCSL clock. The device offers a HCSL

(Host Clock Signal Level) clock output from a clock input reference of

25MHz. The input reference may be derived from an external source

or by the addition of a 25MHz crystal to the on-chip crystal oscillator.

An external reference may be applied to the XTAL_IN pin with the

XTAL_OUT pin left floating.

The device offers spread spectrum clock output for reduced EMI

applications. An I

C bus interface is used to enable or disable spread

spectrum operation as well as select either a down spread value of

-0.35% or -0.5%.

Features

•

Four 0.7V current mode differential HCSL output pairs

Crystal oscillator interface: 25MHz

Output frequency: 100MHz

RMS period jitter: 3ps (maximum)

Output skew: 70ps (maximum)

Cycle-to-cycle jitter: 35ps (maximum)

C support with readback capabilities up to 400kHz

Spread Spectrum for electromagnetic interference (EMI) reduction

3.3V operating supply mode

-40°C to 85°C ambient operating temperature

Available in standard (RoHS 5) and lead-free (RoHS 6) packages
