ICS843001I-22
FEMTOCLOCKSCRYSTAL/LVCMOS-TO-
3.3V, 2.5V LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS843001I-22 is a a highly versatile, low
phase noise LVPECL/LVCMOS Synthesizer
which can generate low jitter reference clocks for
a variety of communications applications and is
a member of the HiPerClocksTM family of high
performance clock solutions from ICS. The dual
crystal interface allows the synthesizer to support up to two
communications standards in a given application (i.e. 1GB
Ethernet with a 25MHz crystal and 1Gb Fibre Channel
using a 25.5625MHz cr ystal). The r ms phase jitter
performance is typically less than 1ps, thus making the
device acceptable for use in demanding applications such
as OC48 SONET and 10Gb Ethernet. The ICS843001I-22
is packaged in a small 24-pin TSSOP package.
FEATURES
One 3.3V or 2.5V LVPECL output pair and
one LVCMOS/LVTTL output
Selectable crystal oscillator interface
or LVCMOS/LVTTL single-ended input
VCO range: 490MHz - 640MHz
Output frequency range: 490MHz - 640MHz
Supports the following applications:
SONET, Ethernet, Fibre Channel, Serial ATA, and HDTV
RMS phase jitter @ 125MHz (1.875MHz - 20MHz):
0.5ps (typical)
Full 3.3V or 2.5V supply modes
-40°C to 85°C ambient operating temperature
Available in both, Standard and RoHS/Lead-Free
compliant packages
