www.DataSheet4U.com PRELIMINARY Integrated Circuit Systems, Inc. ICS844004I-04 FEMTOCLOCKS™CRYSTAL/LVCMOS-TOLVDS FREQUENCY SYNTHESIZER FEATURES Four LVDS outputs Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input Supports the following applications: SONET/SDH, SATA, or 10Gb Ethernet Output frequency range: 140MHz - 170MHz, 560MHz - 680MHz VCO range: 560MHz - 680MHz Crystal oscillator and CLK range: 17.5MHz - 21.25MHz RMS phase jitter @ 622.08MHz output, using a 19.44MHz crystal (12kHz - 20MHz): 0.71ps (typical) RMS phase jitter @ 156.25MHz output, using a 19.53125MHz crystal (1.875MHz - 20MHz): 0.51ps (typical) RMS phase jitter @ 155.52MHz output, using a 19.44MHz crystal (12kHz - 5MHz): 0.75ps (typical) Full 3.3V supply mode -40°C to 85°C ambient operating temperature Available in both standard and lead-free RoHS compliant packages GENERAL DESCRIPTION The ICS844004I-04 is a 4 output LVDS Synthesizer optimized to generate clock HiPerClockS™ frequencies for a variety of high performance applications and is a member of the HiPerClocks TM family of high perfor mance clock solutions from ICS. This device can select its input reference clock from either a crystal input or a singleended clock signal. It can be configured to generate 4 outputs with individually selectable divide-by-one or divide-by-four function via the 4 frequency select pins (F_SEL[3:0]). The ICS844004I-04 uses ICS’ 3 rd generation low phase noise VCO technology...
