ALLENTOWN, Pa. -- Lucent Technologies Inc.'s Microelectronics Group here today unveiled a pair of system-on-a-chip designs that eliminate racks of circuit boards in networking equipment by integrating add/drop multiplexing (ADM), SONET/SDH framing, and data termination in high-speed linear and protected ring optical networks.
According to Lucent Microelectronics, the TADM042G5 and TSOT0410G can cut the cost of system development by up to 70% and reduce the time it takes to ship networking systems by as much as one year. Lucent said its new 0.25-micron devices support synchronous optical network/synchronous digital hierarchy (SONET/SDH) protocols for linear and ring ADM and data termination solutions for optical networks, and operate from 2.5 to 10 gigabits-per-second.
"These are the first true, single-chip solutions that can virtually eliminate racks of silicon," said Ngozi Bell, marketing manager at Lucent Microelectronics. "We've integrated these devices based on a common hardware/software platform that allows designers to build a complete linear/ring network systems supporting rates from 155 Mbps up to 10 Gbps with as few building blocks as possible and with a migration path to higher rates."
The TADM042G5 supports SONET/SDH, Internet Protocol (IP), 10/100/Gigabit Ethernet, asynchronous transfer mode (ATM), point-to-point (PPP), packet-over-SONET (POS), frame relay (FR) and simplified data link (SDL) transmission protocols. The device features software-configurable ports/protocols that reduces system development time for multiple line card applications where previously separate devices/software drivers were needed to handle various protocols associated with the different applications, said Lucent.
The TSOT0410G is a single OC192 and quad OC48 line termination equipment solution. Designed to industry standards, the device was developed to be a seamless interface with the TADM-family for OC192 ring applications. The chip is a SONET/SDH and OC192 framer and a full OC-192 STS1 level pointer processor solution.
Sample volumes of the devices will be available by December and production volumes are slated to begin in the second quarter of next year. The TADM042G5 is priced at $745, while the TSOT0410G sell for less than $1,500 in the U.S. The devices are available in 600-ball laminent BGAs.
