MUX/DeMUX Chipset Lowers Cost Of 2.5-Gbps SONET/SDH

Representing the next generation physical interface chipset for 2.5-Gbps SONET/SDH systems, VSC8161 and VSC8162 highly integrated devices focus on lowering the overall system cost for OC-48/STM-16 telecommunications systems. The devices provide all functions necessary to bridge the gap between a CMOS system core and the laser modules that generate and receive optical signals. Built into the VSC8161 is a 2.5-Gbps clock multiplication unit, 16:1 multiplier, and OC-48/STM-16 laser driver. The VSC8162 offers an OC-48/STM-16 clock and data recovery unit and 1:16 demultiplexer. The devices are intended for use in DWDM systems, SONET/SDH terminal equipment, and SONET/SDH add/drop multiplexers.
