FEMTOCLOCKS DIFFERENTIAL CLOCK
GENERATOR FOR PCI EXPRESS
ICS841604I
IDT / ICS DIFFERENTIAL CLOCK GENERATOR FOR PCI EXPRESS

ICS841604AGI REV. A SEPTEMBER 4, 2007
PRELIMINARY
GENERAL DESCRIPTION
The ICS841604I is an optimized PCIe and sRIO
clock generator and member of the HiPerClocks
family of high-performance clock solutions from
ICS. The device uses a 25MHz parallel crystal to
generate 100MHz and 125MHz clock signals,
replacing solutions requiring multiple oscillator and fanout buffer
solutions. The device has excellent phase jitter (< 1ps rms)
suitable to clock components requiring precise and low-jitter
PCIe or sRIO or both clock signals. Designed for telecom,
networking and industrial applications, the ICS841604I can also
drive the high-speed sRIO and PCIe SerDes clock inputs of
communication processors, DSPs, switches and bridges.
FEATURES
Four differential clock outputs: configurable for PCIe (100MHz)
and sRIO (125MHz) clock signals
Selectable crystal oscillator interface, 25MHz, 18pF parallel
resonant crystal or LVCMOS/LVTTL single-ended reference
clock input
Supports the following output frequencies:
100MHz or 125MHz
VCO: 500MHz
PLL bypass and output enable
RMS phase jitter, 125MHz, using a 25MHz crystal:
0.38ps (typical)
Full 3.3V power supply mode
-40°C to 85°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
