Dual 2ٴ crosspoint switch

The VSC830 contains two independent 2ٴ crosspoints, each one allowing two differential PECL outputs to select from either of two differential PECl inputs. The 2:1 multiplexer tree architecture allows the splitting and selecting of OC-48 signals, or allows two OC-48 signal inputs to be cross-switched among two outputs. The dual 2ٴ configuration allows one package to perform protection switching on the port card. Two crosspoints switch incoming and outgoing service and protection signals serially. Dual configuration also allows one package to provide an asynchronous bypass of a clock and recovery unit for implementing rate-independent WDM systems. The unit is suited to working with the company`s VSC8150 transport overhead protocol monitor in 2.5-Gbit/sec WDM applications. The product is packaged in a 44-pin, 10-mm PQFP and sells for $55 each in quantities of 1000.
