Overview
Integrated Circuit Systems, Inc.
ICS843001I-22 FEMTOCLOCKS™CRYSTAL/LVCMOS-TO3.
3V, 2.
5V LVPECL FREQUENCY SYNTHESIZER FEATURES • One 3.
3V or 2.
5V LVPECL output pair and one LVCMOS/LVTTL output • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input • VCO range: 490MHz - 640MHz • Output frequency range: 490MHz - 640MHz • Supports the following applications: SONET, Ethernet, Fibre Channel, Serial ATA, and HDTV • RMS phase jitter @ 125MHz (1.
875MHz - 20MHz): 0.
5ps (typical) • Full 3.
3V or 2.
5V supply modes • -40°C to 85°C ambient operating temperature GENERAL DESCRIPTION The ICS843001I-22 is a a highly versatile, low phase noise LVPECL/LVCMOS Synthesizer HiPerClockS™ which can generate low jitter reference clocks for a variety of communications applications and is a member of the HiPerClocksTM family of high performance clock solutions from ICS.
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 cr ystal).
The r ms phase jitter performance is typically less than 1ps, thus making the www.

com device acceptable for use in demanding applications such as OC48 SONET and 10Gb Ethernet.
The ICS843001I-22 is packaged in a small 24-pin TSSOP package.
