Industry's First Complete 10Gb/s Line Card Solution

Vitesse Supplies 10Gb/s Integrated Circuits from Analog to Network Processing

Camarillo, CA. Vitesse Semiconductor Corporation (NASDAQ:VTSS) today announced the introduction of integrated circuits for a complete 10Gb/s line card for OC-192/STM-64 SONET/SDH transmissions. This 10Gb/s line card solution includes the VSC7990, a 10Gb/s laser driver; the VSC8171, 10Gb/s 16:1 mux with CMU; the VSC8172, 10Gb/s 1:16 demux with CDR; and the VSC9116, STS-192 transport terminating transceiver. This complete 10Gb/s solution supports Vitesse s commitment to enable communication equipment designers to dramatically decrease overall system cost, while enhancing performance and reducing system time to market.

VSC7990 - Laser Diode Driver Designed to operate with OC-192/STM-64 SONET/SDH lasers, the VSC7990 dramatically lowers the overall system cost while simplifying the implementation of optoelectronic modules. The very fast edge-rates and high modulation current of the VSC7990 enables efficient design of OC-192/STM-64 transmitters for all communications link distances. The VSC7990 has rise and fall times of less than 35ps and very low jitter. It operates from -40° to 125°C. A key feature of the VSC7990 includes operation at 10.7Gb/s, allowing for Forward Error Correction (FEC) that provides signal integrity. The controls for the laser bias and modulation currents, up to 100mA, are directly accessible to external circuitry allowing precise monitoring and setting of the current levels to compensate for aging and optimizing the laser power for link applications. An integrated mux selectable data retiming feature provides the user with a method to recondition the data signal before it is connected to the laser. Differential internal terminated clock and data inputs (50 Ohms) simplify board layout. "The designers of 10Gb/s telecommunications equipment are very constrained by the limited availability of SONET/SDH-quality laser drivers. In addition, directly modulatable lasers are now becoming more prominent in OC-192 system designs," stated Ray Milano, vice president of optoelectronic products at Vitesse. "The VSC7990 provides module and equipment manufacturers with a low cost, high performance driver which produces a data eye with sharp edges," concluded Milano.

VSC8171/72 16-bit Mux/DeMux Chipset The VSC8171 10Gb/s 16:1 multiplexer with clock multiplication unit (CMU) integrates a high speed clock output to re-clock data at the laser driver or to verify jitter performance during operation ensuring SONET compliant data output. This high quality clock output can be disabled to reduce power requirements. The VSC8172 10Gb/s 1:16 demultiplexer integrates the clock and data recovery functions. The low input data sensitivity of 50mV peak-to-peak enables increased distance between repeaters and enhances system margin. For additional flexibility, the VSC8172 incorporates a loss of signal (LOS) output alarm. This chipset supports 10Gb/s to 10.7Gb/s data rates, and can also support higher Forward Error Correction (FEC) rates of up to 12.5Gb/s. Both devices provide a fully differential LVDS industry standard interface maximizing compatibility to supporting devices. The VSC8171 and VSC8172 exceed SONET jitter performance specifications and provide parity checking on the parallel interface ensuring successful transmission of data. "The higher level of integration on the VSC8171 and VSC8172 is a natural continuation of Vitesse s VSC8073/74 chipset and improves the excellent performance of these earlier devices," stated Chris Gardner, V.P. and general manager of telecom products division. "We will continue our 10Gb/s physical layer program with a further reduction in power, and expanded feature sets, while maintaining our price and performance advantage," continued Gardner.

VSC9116 Transport Terminator Transceiver The VSC9116 performs the section and line termination functions, monitors system performance of an STS-192 data transmission, and enhances the byte interleaving/deinterleaving of the STS-48 datastream. The overhead access ports integrated into the VSC9116 allow for insertion and extraction of each overhead byte from the incoming datastream for flexible performance monitoring applications. The four independent section terminations of the VSC9116 enhance system performance while the overhead access ports monitors the system performance. When the VSC9116 is used in conjunction with any one of Vitesse s framer ICs, STS-192 solutions are realized for aggregating STS-3, STS-12 and STS-48 data streams for SONET/ATM/Packet applications, simplifying design. The 4x4 STS-48 granular crosspoint matrix of the VSC9116 allows the designer to groom the incoming and outgoing datastreams for cross-connect and test applications. The crosspoint switches can also be used as a Time Slot Interchange (TSI) fabric with STS-12 level granularity in add/drop mux system applications. The VSC9116 also contains a flexible error insertion capability to assist the test equipment designer. The integrated industry-standard 5 line JTAG boundary scan conforms to IEEE 1149.1 standards and provides the user with full board level testability. A built-in FIFO on the drop side buffering between this device and industry standard ATM/POS UNI devices and can accommodate up to 400ns of skew between datapaths. "The VSC9116 demonstrates Vitesse s continuing efforts to provide products that not only meet today s requirements, but support future high-speed products," continued Gardner. "It also complements our existing V-Frame 2.5TM family 2.5Gb/s products providing a pathway to STS-192 and beyond," concluded Gardner.

The VSC7990 operates from a single +5V or -5.2V supply and dissipate less than 800mW. It is available in die form, further reducing overall system cost and reducing board space requirements. Pricing of the VSC7990 is less than $150, in quantities of 5000. The VSC8171 is packaged in an 80-pin PQFP, while the VSC8172 is packaged in a 100 pin PQFP. Both devices are also available in a 96 BGA package, giving the system designer additional flexibility. Samples will be available in the 2nd quarter of 2000, with production quantities available in the summer. In quantities of 1000, each device is priced at $250. The VSC9116 is packaged in a 720-pin CBGA and dissipates only 8.5W of power, significantly less than competing products. This 2.5V IC is priced at $445 in quantities of 5000 and is sampling now, with production quantities available in May 2000.
