PRELIMINARY

FEMTOCLOCKS

SAS/SATA CLOCK GENERATOR

ICS844441I

Features

•

Designed for use in SAS, SAS-2, and SATA systems

Center (±0.25%) Spread Spectrum Clocking (SSC)

Down (-0.23% or -0.5%) SSC

Better frequency stability than SAW oscillators

One differential 2.5V LVDS output

Crystal oscillator interface designed for 25MHz

= 18pF) frequency

External fundamental crystal frequency ensures high reliability

and low aging

Selectable output frequencies: 75MHz, 100MHz, 150MHz,

300MHz

Output frequency is tunable with external capacitors

RMS phase jitter: 1.33ps (typical)

2.5V operating supply

-40°C to 85°C ambient operating temperature

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

packages

General Description

The ICS844441I is a low jitter, high performance

clock generator and a member of the FemtoClocks™

HiPerClockS™

family of silicon timing products. The ICS844441I is

designed for use in applications using the SAS and

SATA interconnect. The ICS844441I uses an

external, 25MHz, parallel resonant crystal to generate four

selectable output frequencies: 75MHz, 100MHz, 150MHz, and

300MHz. This silicon based approach provides excellent

frequency stability and reliability. The ICS844441I features down

and center spread spectrum (SSC) clocking techniques.
