ICS840004I-01
FEMTOCLOCKS CRYSTAL-TO-
LVCMOS/LVTTL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS840004I-01 is a 4 output LVCMOS/LVTTL
Synthesizer optimized to generate Ethernet
reference clock frequencies and is a member of
the HiPerClocksTM family of high performance
clock solutions from I
DT. Using a 25MHz, 18pF
parallel resonant crystal, the following frequencies can be
generated based on the 2 frequency select pins (F_SEL1:0):
156.25MHz, 125MHz, and 62.5MHz. The ICS840004I-01 uses
I
DT’s 3rd generation low phase noise VCO technology and can
achieve 1ps or lower typical random rms phase jitter, easily
meeting Ethernet jitter requirements. The ICS840004I-01 is
packaged in a small 20-pin TSSOP package.
