Transmitter/Receiver Chipset Joins SONET Family

Added to firm's family of 3.3V high-performance silicon solutions for 2.4 GHz SONET OC-48 applications, the S3041 8-bit transmitter and the S3042 8-bit receiver chip are for SONET/SDH/ATM-based transmission systems and dense wave division multiplexing (DWDM). The S3041 has on-chip clock synthesis phase-locked loop components that allow use of a slower 155.52 MHz external clock reference. In addition, the chip performs all necessary parallel-to-serial functions, clock synthesis, system clock decoupling, line loopback and diagnostic loopback functions in conformance with SONET/SDH transmission standards. The S3042 implements SONET/SDH deserialization, frame detection functions and loopback functions. The chipset can be used as the front-end of SONET systems consisting of serial transmit interface and serial receive.
