TQ8101C
TQ8101C is 622/155 Mb/s SONET/SDH MDFP manufactured by TriQuint Semiconductor.
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 loopback modes for enhanced filed diagnostics
- Frame-synchronous and bytealigned demultiplexer output, pliant with SONET and SDH
- Search, detect, and recovery of framing on out-of-frame input
- Standard TTL and differential or single-ended ECL I/O (except TXCK)
- Tristate TTL output for factory circuit-board testability
- 68-pin Tri Quint MLC controlled-Z surface-mount package with integral heat spreader
