NEWPORT BEACH, Calif.--Conexant Systems Inc. today unveiled the first members in a family of physical-layer (PHY) framing and multiplexing ICs for Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) applications. The framer/multiplexer ICs support 155-megabit-per-second to 10-gigabit/sec. transmission rates used in Internet infrastructure applications
Conexant said it plans to offer a complete line of transceiver and cross-point chip solutions for OC-3 to OC-192 data rates as part of the new series. "With the complete OptiPHY family, we will offer our customers the unique advantage of providing both PHY and transceiver products, all from a single supplier, spanning the full range of data rates and international transmission standards," said Marek Tlalka, product line manager for SONET/SDH in Conexant's Network Access Division in Newport Beach.
The first members in this new series are the OptiPHY-M155 (155 Mbit/sec. OC-3/STM-1) and OptiPHY-M622 (622 Mbit/sec. OC-12/STM-4) SONET/SDH framer/multiplexers. Conexant said it plans to roll out companion PHY products and next-generation transceivers capable of supporting OC-48 (2.5 Gbit/sec.) and OC-192 (10 Gbit/sec.) data rates later this year. The Newport Beach company also said it will offer a family of Plesiochronous Digital Hierarchy (PDH) to SONET/SDH mapper products in the third quarter of 2000.
Conexant cited market projections by International Data Corp. (IDC), which believes SONET/SDH is emerging as the leading technology for backbone transmission systems. The market for standard ICs tailored for SONET/SDH networks grew by more than 50% and it's expected to increase another 40% this year, according to IDC analyst Kimberly Funasaki. Conexant quoted Funasaki as saying the new OptiPHY family "will enable the company to gain an even larger piece of the rapidly-growing pie."
Conexant said its OptiPHY-M155 and OptiPHY-M622 solutions perform SONET/SDH processing, overhead termination and multiplexer/demultiplexer functions. The OptiPHY-M155 has been designed to performs these functions for a single Synchronous Transport Signal (STS-3) or Synchronous Transport Module (STM-1) data stream, said the company.
Meanwhile, the OptiPHY-M622 is a multiport device supporting a single STS-12/STM-4 or four STS-3/STM-1 data streams, Conexant said. Both the OptiPHY-155 and M622 include clock and data recovery (CDR) functionality allowing for a direct connection to optical modules. Conexant said each port in the OptiPHY framers/multiplexers will enable the full-duplex overhead processing of SONET/SDH data streams for section, line and path layers, and also enables framing, alarm detection/insertion, and bit interleaved parity (BIP) error detection.
In quantities of 10,000, the CX29600 OptiPHY-M155 is priced at $70 each. It is housed in a 416-pin 27-by-27 mm super ball-grid array (SBGA) package. The CX29610 OptiPHY-M622 sells for $225 each in 10,000-piece quantities. It is also packaged in a 416-pin SBGA. Samples of the two framer/multiplexers are scheduled to become available in the second quarter with volume deliveries starting by the end of 2000.
