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.

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

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.

• Configurable master or slave

reference clock generation and

PLL bypass for external clocking

Typical SONET/SDH system applications for the TQ8101C include:

• 77.76 MHz or 19.44 MHz output

for the multiplexer; 77.76 MHz or

19.44 MHz and 51.84 MHz

• Transmission system transport cards

• Switch and cross-connect line cards

• Repeaters

• ATM physical layer interfaces

• Test equipment

output for the demultiplexer

• External RC loop filter

• Pass-through mode and three

loopback modes for enhanced

filed diagnostics

• Add/drop multiplexers
