The ICS9112-43/44 is a high speed clock generator designed
to support Gigabit Ethernet system requirements. The
ICS9112-43/44 generates 125 MHz from a 20 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 ICS9112-43/44 with less than 50ps accumulative jitter
is well suited for Gigabit Ethernet applications.
Generates 125 MHz clocks from a 20 MHz crystal
Less than 45ps one sigma jitter (15ps typ.)
Less than ±130ps absolute jitter
Less than 50ps accumulative jitter @ 256 cycles
Rise/fall times less than 1.2ns driving 15pF
On-chip loop filter components
3.0V-5.5V supply range
8-pin, 150-mil SOIC package
Specifically designed to support the high-speed
clocking requirements of Gigabit Ethernet systems.
