AMCC Further Expands FEC Offering With OC-48 Clock & Data Recovery Devices for Metro DWDM and Optical Networking Applications.Business Editors/High-Tech Writers NOTE TO MEDIA: Photo is available in a Smart News Release(TM) on Business Wire's Home Page at www.businesswire.com SAN DIEGO--(BUSINESS WIRE)--Aug. 7, 2000 The S3076 and S3078 Multi-Rate Chips Provide Substantially Reduced Jitter Generation Creating Greater Design Margin for Customers Applied Micro Circuits Corp. (AMCC AMCC Applied Micro Circuits Corporation AMCC Air Mobility Control Center AMCC Ashore Mobile Contingency Communications AMCC Advanced Materials Commercialization Center AMCC allied movement coordination center (US DoD) ) (Nasdaq:AMCC), a leader in high-bandwidth silicon connectivity solutions for the world's optical networks, today announced the S3076, a high-performance multi-rate clock and data recovery unit (CDR (1) See CD-R and extension. (2) (Call Detail Reporting) See call accounting. (3) (Common Data Rate) A standard sampling rate for digital video for 480i and 576i systems. The rate is 13.5 MHz. See ITU-R BT. ) and the S3078 CDR with integrated limiting amplifier. The S3076 and S3078 solutions offer an industry leading combination of jitter generation as low as 3.5 mUI rms and operate at multi-rate with Forward Error Correction A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it. (FEC See forward error correction. FEC - Forward Error Correction ) rates in support of AMCC's existing metro DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing and optical networking solutions. Fabricated in SiGe and fully compliant with ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. , Bellcore and ITU-T See ITU. ITU-T - International Telecommunications Union industry specifications, these devices are also ideally suited for use in SONET/SDH optical module applications. These +3.3V devices offer the industry's best combination of system features such as FEC rates, jitter performance and power consumption including significantly enhanced input sensitivity and programmable Loss-of-Signal (LOS) detection. The S3076 and S3078 perform clock and data recovery for scrambled Non Return to Zero (NRZ (Non-Return-to-Zero) A data transmission method in which the 0s and 1s are represented by different polarities, typically positive for 0 and negative for 1. See NRZI. NRZ - Non Return to Zero ) serial data links with FEC rate capability up to 8 bytes per 255-byte block. In addition, these devices support 1062.5 Mbps for Fibre Channel, 1250 Mbps for Gigabit Ethernet, and 155.52 Mbps through 2488.32 Mbps for OC-3 through OC-48 SONET/SDH applications. The S3076 and S3078 are designed for use as stand alone products and in conjunction with a variety of devices such as AMCC's S3057, S3457 and S3059 transceivers, or the company's S3062 and S3067 multi-rate FEC performance monitor solution. Figure 1 shows a typical network application for these solutions. "Combined with our S3062/67 multi-rate FEC devices, the S3076/78 provides our customers with the best combination of features, jitter performance, power consumption and cost in the industry," said Ken Prentiss, AMCC's director of marketing for telecom products. "The S3076 and S3078 propels AMCC further in the lead with multi-rate solutions for metro optical networks." The S3076 and S3078 incorporate AMCC's proven Phase Locked Loop (PLL) technology, consisting of a phase detector, a loop filter, and a voltage controlled oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air (VCO). The phase detector compares the phase relationship between the VCO output and the serial data input, and the loop filter converts the phase detector output into a smooth DC voltage. The VCO frequency is then varied by this DC voltage input. The multi-rate CDR also contains a lock detect circuit which monitors the frequency and integrity of the incoming serial data. If the received serial data fails the frequency test, the PLL is forced to lock to the local reference clock, thereby maintaining the correct 19.44 MHz/155.52 MHz (19.53 MHz/156.25 MHz for Gigabit Ethernet) or equivalent Fibre Channel frequency of the recovered clock output under loss of signal or loss of clock conditions. Pricing and Availability Both devices are currently in volume production. The S3076, packaged in a 48-pin TQFP See QFP. , is priced at $72 and the S3078, packaged in an 81-pin CBGA CBGA Ceramic Ball Grid Array CBGA Central Banks Gold Agreement CBGA Cascade Boer Goat Association , is priced at $85, both in quantities of 1000.
