Frequency Generator for Fibre Channel Systems
General Description
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 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.
