AMCC introduces industry's lowest cost 622 Mbit s SONET SDH ATM interface circuits.

SAN DIEGO--(BUSINESS WIRE)--Feb. 13, 1995--AMCC (Applied Micro Circuits Corp.) today announced the new 622 Mbit/s SONET/SDH transceiver/receiver and 622 Mbit/s ATM transceiver/receiver.

The chip sets are priced at $99.00/pair and $89.00/pair, respectively, in quantities of 1,000. Similar devices on the market can cost two to three times as much and require more board space. The substantially lower price of AMCC's solution is a direct result of AMCC's high yielding bipolar fabrication process (see attached backgrounder). The AMCC S3017/S3018 SONET/SDH and S3020/S3021 ATM transmitter and receiver chip sets are housed in 10mm square 52-pin thermally enhanced plastic packages and are the smallest footprint devices available.

"AMCC'S S3005/S3006 were the first 622 Mbit/s SONET/SDH/ATM transmitters receivers on the market. As we expand our line, we continue to offer the advantages of low power, small footprint and low price," said Ken Prentiss, network products marketing manager. "AMCC will continue to lead the SONET/SDH/ATM interface market with several product introductions in the coming months."

The S3017/S3018 and S3020/S3021 are fully integrated serialization/deserialization SONET/SDH/ATM 622 Mbit/s interface devices. The circuits are implemented using AMCC's proven on-chip high-frequency Phase Locked Loop (PLL) technology for clock generation and recovery. Both chip sets require only a single +5V supply and handle parallel-to-serial and serial-to-parallel conversion, clock generation and recovery, lock detect, signal detect, local loop back and system timing. The S3017/S3018 chip set can be used to implement the front end of SONET/SDH equipment. The S3020/S3021 chip set is suitable for ATM LAN data communication applications.

The S3017 and S3020 transmitters perform on-chip clock synthesis by using a slower external transmit clock reference. The S3018 and S3021 receiver chips execute clock recovery by synchronizing its on-chip VCO directly to the incoming datastream. The timing circuitry consists of datastream management, framing, and clock distribution throughout the front end. The S3018 and S3021 receiver chips perform SONET/SDH/ATM frame detection. The S3018 and S3021 also provide a lock detect and signal detect feature which indicates that the PLL is locked, or synchronized, to the datastream and facilitates continuous down-stream clocking in the absence of data.

Price and Availability

The S3017/S3018 and S3020/S3021 chip sets are housed in 10mm square 52-pin, thermally enhanced plastic packages. The S3017/S3018 are priced at $99.00/pair in quantities of 1,000. The S3020/S3021 are priced at $89.00/pair in quantities of 1,000. Sample quantities of both chip sets are available now.
