ATM, SONET/SDH PHY Integrate Clock Units

With 8-bit serial-to-parallel and parallel-to-serial data conversion, the VSC8113 and VSC8114 PHY transceivers integrate clock multiplication units (CMUs) for high-speed clock generation and clock and data recovery units (CRUs), and provide SONET/SDH switches, routers, hubs, and test equipment applications with functions that are fully compatible with user network interface (UNI) ICs and optoelectronics modules. The VSC8113 provides 155-Mbps or 622-Mbps operation supporting SONET/SDH compliant physical layers, and the VSC8114 fulfills the requirements of 622-Mbps PHY designs with the addition of parity checking on the low-speed UNI; with a smaller set of functions, this IC operates at lower power than other 622-Mbps transceivers.
