ICS844004I-04
FEMTOCLOCKS™CRYSTAL/LVCMOS-TO-
LVDS FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS844004I-04 is a 4 output LVDS
ICS Synthesizer optimized to generate clock
HiPerClockS™ frequencies for a variety of high performance
applications and is a member of the
HiPerClocksTM family of high performance
clock solutions from ICS. This device can select its input
reference clock from either a crystal input or a single-
ended clock signal. It can be configured to generate 4
outputs with individually selectable divide-by-one or
divide-by-four function via the 4 frequency select pins
(F_SEL[3:0]). The ICS844004I-04 uses ICS’ 3rd generation
low phase noise VCO technology and can achieve 1ps
or lower typical rms phase jitter. This ensures that it
will easily meet clocking requirements for SDH (STM-1/
STM-4/STM-16) and SONET (OC-3/OC12/OC-48). This
device is suitable for multi-rate and multiple port line
card applications. The ICS844004I-04 is conveniently
packaged in a small 24-pin TSSOP package.
FEATURES
• Four LVDS outputs
• Selectable crystal oscillator interface
or LVCMOS/LVTTL single-ended input
• Supports the following applications: SONET/SDH, SATA,
or 10Gb Ethernet
• Output frequency range: 140MHz - 170MHz,
560MHz - 680MHz
• VCO range: 560MHz - 680MHz
• Crystal oscillator and CLK range: 17.5MHz - 21.25MHz
• RMS phase jitter @ 622.08MHz output, using a 19.44MHz
crystal (12kHz - 20MHz): 0.71ps (typical)
• RMS phase jitter @ 156.25MHz output, using a 19.53125MHz
crystal (1.875MHz - 20MHz): 0.51ps (typical)
• RMS phase jitter @ 155.52MHz output, using a 19.44MHz
crystal (12kHz - 5MHz): 0.75ps (typical)
• Full 3.3V supply mode
• -40°C to 85°C ambient operating temperature
• Available in both standard and lead-free RoHS compliant
packages
