FEMTOCLOCKS CRYSTAL-TO-3.3V
LVPECL FREQUENCY SYNTHESIZER
ICS843004-01
IDT / ICS 3.3V LVPECL FREQUENCY SYNTHESIZER

ICS843004-01 REV B JUNE 30, 2006
GENERAL DESCRIPTION
The ICS843004-01 is a 4 output LVPECL
synthesizer optimized to generate Ether net
reference clock frequencies and is a member of
the HiPerClocksTM 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’
3rd 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.
FEATURES
Four 3.3V LVPECL outputs
Selectable crystal oscillator interface
or LVCMOS/LVTTL single-ended input
Supports the following output frequencies:
156.25MHz, 125MHz and 62.5MHz
VCO range: 560MHz - 680MHz
RMS phase jitter @ 156.25MHz, using a 25MHz crystal
(1.875MHz - 20MHz): 0.57ps (typical)
RMS phase noise at 156.25MHz (typical)
Phase noise:
