Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

The ICS9112-32 are high-speed clock generators designed to support fibre channel system requirements. The ICS9112- 31/32 generates 106.25 MHz from a 25 MHz crystal.

An exact frequency multiplying ratio of the ICS9112-32 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 ICS9112-32 with less than 25ps accumulative jitter is well suited for Fibre Channel applications
