integrated circuit systems, inc. general description features ICS9112-33/34 block diagram frequency generator for fibre channel systems applications ICS9112-33/34 rev d 3/3/99 the ICS9112-33/34 are high-speed clock generators designed to support fibre channel system requirements. the ics9112- 33/34 generates 106.25 mhz from a 21.25 mhz crystal. an exact frequency multiplying ratio ensures better than 100 ppm frequency accuracy using a standard at crystal with external load capacitors (typically 33pf5% for an 18pf load crystal). achieving 100 ppm over four years requires the crystal to have a 20 ppm initial accuracy, 30 ppm temperature and 5 ppm/year aging coefficients. the ICS9112-33/34 with less than 25ps accumulative jitter is well suited for fibre channel applications. crystal: ec-21.25m (ecliptek) ? generates 106.25 mhz clocks from a 21.25 mhz crystal ? less than 45ps one sigma jitter (10ps typ.) ? less than 130ps absolute jitter ? less than 25ps accumulative jitter @ 256 cycles ? rise/fall times less than 1.2ns driving 15pf ? on-chip loop filter components ? 3.0v-5.5v supply range ? 8-pin, 150-mil soic package ? specifically designed to support the high-speed clocking requirements of fibre channel systems. product preview documents contain information on new products in the sampling or preproduction phase of development. characteristic data and other specifications are subject to change without notice. preliminary product preview
