Vitesse Introduces 64x64 Crosspoint Switch IC for High-Speed Automated Test Equipment, Video and Optical Cross-Connect Applications October 19, 1998 08:13 AM CAMARILLO, Calif.--(BUSINESS WIRE)--Oct. 19, 1998--Vitesse Semiconductor Corp. (VTSS) Monday introduced the VSC6464, a 64x64 crosspoint switch IC. At 500Mb/s, the VSC6464 is the fastest off-the-shelf crosspoint switch of its size and is ideal for ATE applications, video and optical networks. The VSC6464 provides a large switch fabric, 64 x 64, with two modes of operation: synchronous and asynchronous. In the synchronous mode, inputs and outputs are clocked and data can be transferred at a rate of up to 250Mb/s. In the asynchronous mode, the input registers are bypassed and data can be transferred at a rate of up to 500Mb/s. In the asynchronous mode, skew is less than 1.5ns from any input to any output, and less than 750ps between outputs in the synchronous mode. In both modes of operation, the VSC6464 is fully nonblocking, allowing any output to be connected to any input, regardless of the configurations of other outputs. The VSC6464 is designed for use in ATE and video applications. The VSC6464 provides a high-capacity switch core for OC-3 optical cross-connects and for SMPTE-259 video switches and routers. In ATE equipment, the crosspoint switch may be used either as part of the algorithmic pattern generator (ALPG) or as part of the timing generator (TG). As part of the ALPG, crosspoint switches are frequently used for pattern switching or to scramble addresses for memory testing. In shared-resource testers, a crosspoint switch can be used to route timing signals inside the TG. "Until now, a combination of several smaller switches, such as 8x8s or 32x32s, have been required for a 64x64 crosspoint function. Such a combination uses a large amount of board space and has high power dissipation," stated Allan Armstrong, product marketing manager of Vitesse's ATE Division. "With the VSC6464, the total system cost is reduced, since fewer ICs are used. And the nonblocking architecture of the VSC6464 simplifies video, ATE and optical cross-connect designs," concluded Armstrong. The VSC6464 typically dissipates 5 Watts from a single -2 Volt supply and is packaged in an industry-standard 208-pin 28mm x 28mm plastic PQFP. Samples of the VSC6464 are available now, with volume production scheduled for the first quarter of 1999. In quantities of 100, the VSC6464 is priced at $485.
