FEMTOCLOCKSCRYSTAL-TO-LVCMOS/LVTTL
FREQUENCY SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS840008-01 is an 8 output LVCMOS/LVTTL
Synthesizer designed to generate 125MHz for
Gigabit Ethernet applications and is a member of
the HiPerClocksTM family of high performance clock
solutions from ICS. The ICS840008-01 uses ICS’
3rd generation low phase noise VCO technology and can achieve
1ps or lower typical random rms phase jitter, easily meeting
Gigabit Ethernet jitter requirements. The ICS840008-01 is
packaged in a small 24-pin SSOP package.
FEATURES
Eight LVCMOS/LVTTL outputs, 15
typical output impedance
Output frequency range: 125MHz - 160MHz
Crystal oscillator interface, 25MHz - 32MHz crystal
VCO range: 500MHz - 640MHz
RMS phase jitter (1.875MHz - 20MHz): 0.52ps (typical)
Output skew: 150ps (maximum) (design target)
Voltages supply modes:
