FEMTOCLOCKS CRYSTAL-TO-LVCMOS/
LVTTL FREQUENCY SYNTHESIZER
ICS840004
IDT / ICS LVCMOS FREQUENCY SYNTHESIZER
1
ICS840004AG REV B AUGUST 16, 2006
GENERAL DESCRIPTION
The ICS840004 is a 4 output LVCMOS/LVTTL
Synthesizer optimized to generate Ether net
reference clock frequencies and is a member of the
HiPerClocksTM family of high performance clock
solutions from IDT. Using a 26.5625MHz, 18pF
parallel resonant crystal, the following frequencies can be
generated based on the 2 frequency select pins (F_SEL1:0):
212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and
53.125MHz. The ICS840004 uses IDT’s 3rd generation low phase
noise VCO technology and can achieve 1ps or lower typical
random r ms phase jitter, easily meeting Ether net jitter
requirements. The ICS840004 is packaged in a small 20-pin
TSSOP package.
