PRELIMINARY

FEMTOCLOCKS™ CRYSTAL-TO-LVDS

FREQUENCY SYNTHESIZER

ICS844001-21

GENERAL DESCRIPTION

FEATURES

The ICS844001-21 is a a highly versatile, low

• One differential LVDS output pair and

one LVCMOS reference output

ICS

phase noise LVDS Synthesizer which can generate

low jitter reference clocks for a variety of

communications applications and is a member of

the HiPerClocks^TMfamily of high performance clock

HiPerClockS™

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

solutions from IDT. The dual crystal interface allows the

synthesizer to support up to two communications standards in

a given application (i.e. 1GB Ethernet with a 25MHz crystal

and 1Gb Fibre Channel using a 25.5625MHz crystal). The rms

phase jitter performance is typically less than 1ps, thus making

the device acceptable for use in demanding applications such

as OC48 SONET and 10Gb Ethernet. The ICS844001-21 is

packaged in a small 24-pin TSSOP package.

• VCO range: 560MHz - 700MHz

• Supports the following applications:

SONET, Ethernet, Fibre Channel, Serial ATA, and HDTV

• RMS phase jitter @ 622.08MHz (12kHz - 20MHz):

0.92ps (typical)

• Full 3.3V supply mode

• 0°C to 70°C ambient operating temperature

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