integrated circuit systems, inc. general description features ics9107c-21 ics9107c-22 block diagram frequency generator for fibre channel systems applications 9107 -21 /22 rev c 9/14/99 the ics9107c-21 and ics9107c-22 are high-speed clock generators designed to support fibre channel system requirements. the ics9107c-21 generates a single copy of the 106.25 mhz from a 17 mhz crystal. the ics9107c-22 provides a second copy of the 106.25 mhz clock with output skew less than 100ps. 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. ? generates one or two 106.25 mhz clocks from a 17 mhz crystal ? less than 60ps one sigma jitter ? less than 200ps absolute jitter ? output skew less than 100ps on two channel version (-22) ? rise/fall times less than 4ns driving 15pf ? on-chip loop filter components ? 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
