ICS843011C

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.
