ESCRIPTION
The ICS843002I-01 is a 2 output LVPECL
synthesizer optimized to generate Ethernet
reference clock frequencies and is a member
of the HiPerClocks
TM
family of high perfor-
mance clock solutions from ICS. Using a
25MHz 18pF parallel resonant crystal, the following
frequencies can be generated based on the 2 frequency
select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and
62.5MHz. The ICS843002I-01 uses ICS’ FemtoClock
TM
low phase noise VCO technology and can achieve 1ps
or lower typical rms phase jitter, easily meeting Ethernet
jitter requirements. The ICS843002I-01 is packaged in a
small 20-pin TSSOP package.
