PRELIMINARY Integrated Circuit Systems, Inc. ICS843004-02 www.DataSheet4U.com CRYSTAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER FEATURES Four 3.3V LVPECL outputs Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input Crystal input range: 14MHz - 37.78MHz VCO Range: 560MHz - 680MHz Supports the following applications: SONET, Ethernet, Serial ATA, SCSI and HDTV RMS phase jitter @ 155.52MHz (12kHz - 20MHz): 0.91ps (typical) Offset Noise Power 100Hz ............... -97.1 dBc/Hz 1kHz .............. -121.6 dBc/Hz 10kHz .............. -124.9 dBc/Hz 100kHz .............. -125.1 dBc/Hz Full 3.3V supply mode 0°C to 70°C ambient operating temperature M Divider Value 18 24 24 32 32 32 32 40 N Divider Value 3 4 8 1 2 4 8 8 GENERAL DESCRIPTION The ICS843004-02 is a 4 output LVPECL Synthesizer optimized to generate clock HiPerClockS™ frequencies for a variety of high performance applications and is a member of the HiPerClocksTM family of high performance clock solutions from ICS. This device can select its input reference clock from either a crystal input or a single-ended clock signal and can be configured to generate a number of different output frequencies via the 3 frequency select pins (F_SEL2:0). The ICS843004-02 uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter. This ensures that it will easily meet clocking requirements for high-speed communication protocols such as 10 and 12 Gigabit Ethern...
