ICS844011I Datasheet | ICS

.. PRELIMINARY Integrated Circuit Systems, Inc. FEMTOCLOCKS™ CRYSTAL-TO- LVDS CLOCK GENERATOR Features - (1) Differential LVDS output - Crystal oscillator interface, 18p F parallel resonant crystal (20.4MHz - 28.3MHz) - Output frequency range: 81.66MHz - 113.33MHz - VCO range: 490MHz - 680MHz - RMS phase jitter @ 106.25MHz, using a 26.5625MHz crystal (637k Hz - 10MHz): 0.75ps (typical) - 3.3V or 2.5V operating supply - -40°C to 85°C ambient operating temperature GENERAL DESCRIPTION The ICS844011I is a Fibre Channel Clock Generator and a member of the Hi Per Clocks TM Hi Per Clock S™ family of high performance devices from ICS. The ICS844011I uses an 18p F parallel resonant crystal over the range of 20.4MHz - 28.3MHz. For Fibre Channel applications, a 26.5625MHz crystal is used. The ICS844011I has excellent <1ps phase jitter performance, over the 637k Hz - 10MHz integration range. The ICS844011I is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
