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:
