ICS843001-21

FEMTOCLOCKS™ C RYSTAL-TO-3.3V LVPECL

FREQUENCY SYNTHESIZER

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS843001-21 is a a highly versatile, low

• One 3.3V LVPECL output pair and one LVCMOS output

ICS

HiPerClockS™

phase noise LVPECL 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 solutions from ICS.The dual

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

• VCO range: 560MHz - 700MHz

• Supports the following applications:

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

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 ICS843001-21

is packaged in a small 24-pin TSSOP package.

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

0.80ps (typical)

Offset

Noise Power

100Hz ............... -60.3 dBc/Hz

1kHz ............... -88.5 dBc/Hz

10kHz ............. -111.9 dBc/Hz

100kHz ............. -113.0 dBc/Hz

• Full 3.3V supply mode

• 0°C to 70°C ambient operating temperature

• Available in both standard and lead-free RoHS-compliant

packages
