ICS844071I

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO- LVDS

CLOCK GENERATOR

GENERAL DESCRIPTION

FEATURES

• (1) Differential LVDS output

The ICS844071I is a Serial ATA (SATA)/Serial

ICS

Attached SCSI (SAS) Clock Generator and a

member of the HiPerClocks^TMfamily of high

performance devices from ICS.The ICS844071I

uses an 18pF parallel resonant crystal over the

HiPerClockS™

• Crystal oscillator interface, 18pF parallel resonant crystal

(20.833MHz - 28.3MHz)

• Output frequency range: 62.5MHz - 170MHz

• VCO range: 500MHz - 680MHz

range of 20.833MHz - 28.3MHz. For SATA/SAS applications,

a 25MHz crystal is used and either 75MHz or 150MHz may

be selected with the FREQ_SEL pin. The ICS844071I has

excellent <1ps phase jitter performance, over the 12kHz -

20MHz integration range. The ICS844071I is packaged in a

small 8-pin TSSOP, making it ideal for use in systems with

limited board space.

• RMS phase jitter @ 150MHz, using a 25MHz crystal

(12kHz - 20MHz): 0.75ps (typical)

• 3.3V or 2.5V operating supply

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

• Replaces ICS844051-11
