ICS843001I-23

PRELIMINARY Integrated Circuit Systems, Inc. ICS843001I-23 FEMTOCLOCKS™ CRYSTAL-TO-3.3V LVPECL/LVCMOS FREQUENCY SYNTHESIZER FEATURES One 3.3V LVPECL output pair and one LVCMOS/LVTTL REF_OUT output Selectable crystal oscillator interfaces or LVCMOS/LVTTL single-ended input Crystal and CLK range: 17.5MHz - 29.54MHz Able to generate GbE/10GbE/12GbE, Fibre Channel (1Gb/4Gb/10Gb), PCI-E and SATA from a 25MHz crystal VCO range: 1.12GHz - 1.3GHz Supports the following applications: SONET, Ethernet, Fibre Channel, Serial ATA, and HDTV RMS phase jitter @ 622.08MHz (12kHz - 20MHz): <1ps (typical) design target Supply modes: VCC/VCCO 3.3V/3.3V 3.3V/2.5V 2.5V/2.5V -40°C to 85°C ambient operating temperature Available in both standard and lead-free RoHS-compliant packages GENERAL DESCRIPTION The ICS843001I-23 is a highly versatile, low IC S phase noise LVPECL/LVCMOS Synthesizer HiPerClockS™ which can generate low jitter reference clocks for a variety of communication 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 three communication standards in a given application (i.e. SONET with a 19.44MHz crystal, 1Gb/10Gb Ethernet and Fibre Channel using a 25MHz crystal). The rms phase jitter performance is typically less than 1ps, thus www.DataSheet4U.com making the device acceptable for use in demanding applications such as OC48 SONET, GbE/10Gb Ethernet a...
