The ICS844004I-04 is a 4 output LVDS Synthesizer optimized to generate clock HiPerClockSTM frequencies for a variety of high performance applications and is a member of the HiPerClocks TM f amily 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 g eneration 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 SDH (STM-1/ STM-4/STM-16) and SONET (OC-3/OC12/OC-48). This device is suitable for multi-rate and multiple por t line card applications. The ICS844004I-04 is conveniently packaged in a small 24-pin TSSOP package.
