Frequency Generator for Fibre Channel Systems

General Description

The ICS9112-35/36 are high-speed clock generators designed

to support fibre channel system requirements. The ICS9112-

35/36 generates 106.25 MHz from a 17 MHz crystal.

An 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 ICS9112-35/36 with less than 40ps accumulative jitter

is well suited for Fibre Channel applications.
