New Product Announcement Complete Chipset Integrates Four OC-12 Data Streams to One OC-48 Optical Interface Applied Micro Circuits Corp.,(AMCC)(R),(Nasdaq:AMCC), a leader in high-bandwidth silicon connectivity solutions, today announced the S3045, a CMOS SONET/SDH section terminator transceiver used for integrating four STS-12/STM-4 data streams into a single STS-48/STM-16 data stream. Combined with the S3041 transmitter and S3042 receiver, the three chipset reduces power consumption by an astounding 350% over competing solutions, setting a new precedent in power reduction for OC-48 solutions. The S3041/42/45 chipset's compatibility with both off-the-shelf and proprietary solutions, guaranteed compliance with ANSI, Bellcore, and ITU-T specifications and 2.5 GHz operation make it the ideal solution for designers of both SONET/SDH-based and Wavelength Division Multiplexing (WDM) applications. As part of the OC-48 Silicon Sonet Transport (SST)(tm) solution, AMCC's S3041 (transmitter) and S3042 (receiver) chipset adds superior jitter performance, low power consumption and superior economics to the tremendous power reduction benefits of the S3045. "To achieve our power, price and performance design goals, we distributed functions that require high-speed bipolar process technology to the S3041 and S3042, and incorporated lower-speed functions into the low-power CMOS S3045. The result was a superior solution that maximizes speed and minimizes power consumption," said Ken Prentiss, AMCC's product marketing manager for SONET/SDH/ATM. "These advantages enable our customers to design high-speed off-the-shelf and proprietary SONET and WDM-based systems with less than one third the power of current competitive alternatives." On the network interface side, the S3045 transmits and receives 8-bit parallel, 77 MHz low voltage TTL (LVTTL) data streams from industry standard devices such as PMC-Sierra's PM5355 SUNI-622. On the high-speed side, the S3045 transmits and receives 8-bit parallel, 311 MHz low voltage differential signal (LVDS) data streams between the S3041 and S3042. The attached diagram (Figure 1) illustrates a typical network application using the S3045. To ensure communications integrity, the S3045 calculates and inserts Byte Interleaved Parity (B1). The S3045 also performs optional frame synchronous scrambling and descrambling, inserts section-trace bytes (JO/ZO) in the transmit path and calculates even and odd parity over data or data and frame pulse. The S3045 ensures optimal performance while Out of Frame (OOF) and Loss of Frame (LOF) are used to provide monitor and alarm signals to indicate in-frame and out-of-frame states of the incoming signal. The S3041 transmitter chip performs all parallel-to-serial, clock synthesis, system decoupling, line loopback and diagnostic loopback functions, while the S3042 receiver chip performs all serial-to-parallel and framing functions. As the industry's leading single power supply fully-integrated SONET OC-48 interface devices, the S3041 and S3042 support 1.25 GHz operation, and are fully-compliant with SONET/SDH transmission standards. Pricing and Availability Samples of the S3045 are available now with production release scheduled for fourth quarter CY, 1998. The S3045, packaged in a 208-pin PQFP, is priced at $192 in quantities of 100. AMCC is a premier supplier of high-bandwidth silicon connectivity for the world's communication infrastructure.
