Overview
PRELIMINARY Integrated Circuit Systems, Inc.
ICS843011C FEMTOCLOCKS™ CRYSTAL-TO3.
3V LVPECL CLOCK GENERATOR FEATURES • One differential 3.
3V LVPECL output • Crystal oscillator interface designed for 26.
5625MHz 18pF parallel resonant crystal • Output frequency: 106.
25MHz or 100MHz • VCO range: 560MHz - 680MHz • RMS phase jitter @ 100MHz, using a 25MHz crystal (637kHz - 10MHz): 0.
29ps (typical) • 3.
3V operating supply • -40°C to 85°C ambient operating temperature • Available in both standard and lead-free RoHS compliant packages GENERAL DESCRIPTION The ICS843011C is a Fibre Channel Clock Generator and a member of the HiPerClocksTM HiPerClockS™ family of high performance devices from ICS.
The ICS843011C uses a 26.
5625MHz crystal to synthesize 106.
25MHz or a 25MHz crystal to synthesize 100MHz.
The ICS843011C has excellent <1ps phase jitter performance, over the 637kHz – 10MHz integration range.
The ICS843011C is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
