Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

The ICS844004I-04 is a 4 output LVDS Synthesizer optimized to generate clock 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 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' 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 SDH (STM-1/ STM-4/STM-16) and SONET (OC-3/OC12/OC-48). This device is suitable for multi-rate and multiple port line card applications. The ICS844004I-04 is conveniently packaged in a small 24-pin TSSOP package.
