ESCRIPTION
The ICS843001I-22 is a a highly versatile, low
phase noise LVPECL/LVCMOS Synthesizer
which can generate low jitter reference clocks for
a variety of communications applications and is
a member of the HiPerClocks
TM
family of high
performance clock solutions from ICS. The dual
crystal interface allows the synthesizer to support up to two
communications standards in a given application (i.e. 1GB
Ethernet with a 25MHz crystal and 1Gb Fibre Channel
using a 25.5625MHz crystal). The rms phase jitter
performance is typically less than 1ps, thus making the
device acceptable for use in demanding applications such
as OC48 SONET and 10Gb Ethernet. The ICS843001I-22
is packaged in a small 24-pin TSSOP package.
