TQ8101C中文资料TriQuint数据手册PDF规格书

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.

• 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, compliant 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 TriQuint MLC controlled-Z surface-mount package with integral heat spreader

• Dual-supply operation (+5V, –5.2V)

• Low power dissipation (2.3W nom.)
