PRELIMINARY

PCI EXPRESS™ CLOCK GENERATOR

ICS841S04I

GENERAL DESCRIPTION

FEATURES

• Four 0.7V current mode differential HCSL output pairs

The ICS841S04I is a PLL-based clock generator

ICS

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

HiPerClockS™

• Crystal oscillator interface, 25MHz

• Output frequency: 100MHz

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.

• RMS period jitter: 3ps (maximum)

• Output skew: 70ps (maximum)

• Cycle-to-cyle jitter: 35ps (maximum)

• I²C support with readback capabilities up to 400kHz

The device offers spread spectrum clock output for reduced EMI

applications. An I²C 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%.

• Spread Spectrum for electromagnetic interference (EMI)

reduction

• 3.3V operating supply mode

The ICS841S04I is available in both standard and lead-free

24-Lead TSSOP packages.

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

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

packages
