S a General atDescription The ICS9112-31/32 are high-speed clock generators designed .D to support fibre channel system requirements. The ICS9112w 31/32 w generates 106.25 MHz from a 25 MHz crystal. wAn exact frequency multiplying ratio ensures better than ±100 ppm frequency accuracy using a standard AT crystal
with external load capacitors (typically 33pF ±5% 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 ICS9112-31/32 with less than 25ps accumulative jitter is well suited for Fibre Channel applications.
