TQ8101C

T R I Q U I N T S E M I C O N D U C T O R, I N C . TQ8101C The TQ8101C is a SONET/SDH transceiver that integrates Multiplexing, Demultiplexing, SONET/SDH Framing, clock synthesis PLL (MDFP), and loopback functions in a single monolithic integrated circuit. Implementation with the TQ8101C requires only a simple external RC loop filter and standard TTL and ECL power supplies. For optimal performance, the TQ8101C MDFP is packaged in a 68-pin multilayer ceramic (MLC) surface-mount package with an integral CuW heat spreader. The TQ8101C provides an integrated solution for physical interfaces intended for use in STS-12/STM-4 (622.08-Mb/s) and STS-3/STM-1 (155.52-Mb/s) SONET/SDH systems. The TQ8101C meets ANSI, Bellcore, and ITU requirements for a SONET/ SDH device. With a 51.84-MHz reference clock, the phase-locked loop (PLL) provides 77.76-MHz or 19.44-MHz output for the multiplexer and 77.76-MHz or 19.44-MHz and 51.84-MHz output for the demultiplexer. Typical SONET/SDH system applications for the TQ8101C include: TELECOM PRODUCTS 622/155 Mb/s SONET/SDH MDFP Features Byte-wide Multiplexing, Demultiplexing, Framing, and PLL (MDFP) in one device Choice of STS-12/STM-4 or STS-3/STM-1 transmission rates Configurable master or slave reference clock generation and PLL bypass for external clocking 77.76 MHz or 19.44 MHz output for the multiplexer; 77.76 MHz or 19.44 MHz and 51.84 MHz output for the demultiplexer External RC loop filter Pass-through mode and three lo...
