ESCRIPTION
The ICS843004-01 is a 4 output LVPECL
synthesizer optimized to generate Ethernet
reference clock frequencies and is a member of
the HiPerClocks
TM
family of high performance clock
solutions from ICS. Using a 25MHz 18pF parallel
resonant crystal, the following frequencies can be generated
based on the settings of 2 frequency select pins (F_SEL[1:0]):
156.25MHz, 125MHz, 62.5MHz. The ICS843004-01 uses
ICS’ 3
rd
generation low phase noise VCO technology and can
achieve 1ps or lower typical rms phase jitter, easily meeting
Ethernet jitter requirements. The ICS843004-01 is packaged
in a small 24-pin TSSOP package.
