PRELIMINARY

FEMTOCLOCKS™ DIFFERENTIAL CLOCK

GENERATOR FOR PCI EXPRESS

ICS841604I

GENERAL DESCRIPTION

FEATURES

The ICS841604I is an optimized PCIe and sRIO

• Four differential clock outputs: configurable for PCIe (100MHz)

and sRIO (125MHz) clock signals

ICS

HiPerClockS™

clock generator and member of the HiPerClocks™

family of high-performance clock solutions from

• Selectable crystal oscillator interface, 25MHz, 18pF parallel

resonant crystal or LVCMOS/LVTTL single-ended reference

clock input

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.

• 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)
