Chipset Touts LowPower Dissipation Spec

A cost savings of 50% and a power reduction of 30% are promised with the VSC8173 16:1 multiplexer and VSC8174 1:16 demultiplexer, a 10 Gbps chipset for OC-192 and STM-64 applications. The reduced power requirements minimizes heat sink, airflow, and power supply requirements, making the chipset suited for telecomm, dense wavelength division multiplexing, undersea transmission and test equipment. Both chips operate at the standard OC-192 rate of 9.953 Gbps and higher data rates to support Forward Error Correction capability. The VSC8173 multiplexer with clock multiplication unit integrates a high-speed clock output to re-clock data at the laser driver. The companion chip, the VSC8174 is the demultiplexer that incorporates the clock and data recovery functions. The 3.3V chips are available in 14-mm, 100-pin PQFP or 96 ball BGA packages. The chipset, including both chips, is priced at $500 each/1,000.
