Despite the availability of a range of commodity products, designers often need to turn to custom devices to meet particular needs. But which technology best suits the application? Should you base your design around an FPGA or is it better to use an ASIC? Can you meet your design requirements using a DSP?

In this section, New Electronics brings you the latest developments from the advanced platforms market, looking at how to develop and apply FPGA, ASIC and DSP technology.

FPGA industry rises to the challenge of 28Gbit/s transceivers

At last month's European Conference and Exhibition on Optical Communication, Altera demonstrated an fpga implementing a 100Gbit/s link using four 28Gbit/s transceivers. The Stratix V GT fpga, working alongside chipmaker Gennum's clock data recovery circuits, used the transceivers –each operating at 25.8Gbit/s – to send 100Gbit/s of data over 7in of Nelco 4000-13 pcb material, exceeding the specification requirement of 4in.

CPLD flexibility enables wide application

Once simple to understand, programmable logic is now a complex world, with devices of all types apparently providing solutions to most design requirements. Despite this wide range of solutions, the industry's focus remains assuredly on the leading edge.
