ESCRIPTION
The ICS8430252-45 is a 2 output LVPECL and
LVCMOS/LVTTL Synthesizer optimized to gen-
erate Ethernet reference clock frequencies and
is a member of the HiPerClocks family of high
performance clock solutions from ICS. Using a
25MHz, 18pF parallel resonant crystal, the following fre-
quencies can be generated: 156.25MHz LVPECL output
and, 125MHz LVCMOS output. The 8430252-45 uses ICS’
3rd generation low phase noise VCO technology and can
achieve 1ps or lower typical rms phase jitter, easily meet-
ing Ethernet jitter requirements. The ICS8430252-45 is
packaged in a small 16-pin TSSOP package.
