Applications
9107C-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 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.
• 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
