PRELIMINARY

FEMTOCLOCKS™ CRYSTAL-TO-LVDS

CLOCK GENERATOR

ICS844021-01

GENERAL DESCRIPTION

FEATURES

• One Differential LVDS output

The ICS844021-01 is an Ethernet Clock Generator

ICS

HiPerClockS™

and a member of the HiPerClocks^TMfamily of high

performance devices from IDT. The ICS844021-01

uses an 18pF parallel resonant crystal over the

range of 24.5MHz - 34MHz. For Ethernet appli-

• Crystal oscillator interface, 18pF parallel resonant crystal

(24.5MHz - 34MHz)

• Output frequency range: 122.5MHz - 170MHz

• VCO range: 490MHz - 680MHz

cations, a 25MHz crystal is used. The ICS844021-01 has

excellent <1ps phase jitter performance, over the 1.875MHz -

20MHz integration range. The ICS844021-01 is packaged in a

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

limited board space.

• RMS phase jitter @ 125MHz, using a 25MHz crystal

(1.875MHz - 20MHz): 0.45ps (typical)

• 3.3V or 2.5V operating supply

• 0°C to 70°C ambient operating temperature

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