Xilinx Inc. and Brilliant Telecommunications Inc., a developer timing solutions, have partnered to deliver the industry's first carrier-class FPGA-based network timing solution for next generation wired and wireless networks.

The solution provides next-generation communication network designers with the first embedded programmable timing solution, delivering unparalleled flexibility, field upgradeability and customization. By integrating timing functions into Xilinx FPGAs, the solution offers significant cost savings. Implemented using a Xilinx Virtex or Spartan FPGA, the solution is delivered in the form of two IP cores, NGNTime and FemtoTime. The cores are fully interoperable with the industry's Network Timing Protocol (NTP) and provide a migration path for Version 2 of IEEE 1588 or Precision Time Protocol (PTP).

The offerings mitigate technology risk by allowing use of the widely deployed NTP protocol while providing a migration path to the telecom focused PTP protocol using the same hardware. The solution provides accurate timing from ingress to egress points across an entire (end-to-end) network to support next-generation applications such as wireless base stations, femtocell access points, IPTV routers/switches and mobile backhaul. Leveraging Xilinx FPGAs, users can customize embedded solutions for equipment manufactures by integrating precise timing in their products while expediting time-to-market.

Xilinx and Brilliant participated at a recent IEEE 1588 PTP plug-fest, the 2007 International IEEE Symposium on Precision Clock Synchronization for Measurement, Control and Communication (ISPCS) in October. The plug-fest provided an opportunity to test and demonstrate device and system interoperability of the new solution and resolve compatibility issues.

The solution is immediately available.
