Integrated Device Technology Inc. (IDT) has announced the introduction of a jitter attenuator (ICS874003AG-02) optimised for the Xilinx Virtex-4 family of FPGAs. Designed to support PCI Express (PCIe), this component is a first timing device capable of attenuating the jitter from a 100MHz PCIe input clock, while translating it to a 250MHz LVDS output. Removing the jitter from the signal enables original equipment manufacturers using the Virtex-4 RocketIO transceivers to achieve 2.5Gbps throughput —a critical specification for PCIe communications applications.

This device is based on IDT's FemtoClock technology, designed to cost-effectively generate reference clocks with low, sub-1ps RMS phase-noise to meet the jitter requirements of PCIe-based communication applications.

"Our strength in this area, coupled with our ongoing commitment to standards-based technologies, such as PCI Express, gives us the technical foundation and relevant applications expertise to develop a truly unique, silicon-based timing solution that meets the growing needs of our customers and the broader market," said Fred Zust, vice president and general manager for the IDT NetCom clock division.

The IDT PCI Express jitter attenuator is available in both a standard as well as RoHS-compliant 20-pin TSSOP package. The product is being sampled and is priced at Rs.213.76 ($4.60) in 10,000 unit quantities. An evaluation board is also available to aid the verification process.
