Nashua, N.H. Teradyne is joining forces with Accelerant to make 6.25-Gbps backplanes a reality for communications designers. Under a strategic development agreement, the companies will develop a backplane reference design consisting of Teradyne's connector solutions and Accelerant's transceiver products.
The joint reference design integrated Accelerant's AN5500 backplane transceiver with Teradyne's VHDM-HSD connector. The reference design consists of the VHDM connector in FR4 with a maximum of 32-in. traces, two line cards based on the AN5500, SMA cables, and power supply cables. The platform requires and external power supply and connects to a PC to enable software access and control.
The AN5500 is a five-port transceiver that can achieve 6.25-Gbps data rates per port, leading to an aggregate through put of roughly 25 Gbps. The transceiver draws 4-W power and can operate over 48-in. of FR-4.
Teradyn'e VHDM-HSD connector was developed in 1999 and is available in 5-, 6-, and 8-row versions. This connector is employed in communications, storage, and server designs.
The joint backplane reference design is supplied with schematics, layout, models, and a set of software tools. Information about this reference design is available at http://www.accelerant.net/products/refdesplatform.
