Vitesse Introduces CMOS Quad Gigabit Ethernet/Fibre Channel Compliant Interconnect IC CAMARILLO, Calif.--(BUSINESS WIRE)--May 10, 1999--Vitesse Semiconductor Corporation (Nasdaq:VTSS) today introduced the newest member of the Velocity Family of high performance CMOS serial communication ICs, the VSC7216 -- a quad multi-gigabit interconnect IC that is ideal for high bandwidth bus, backplane and system-to-system connections. The VSC7216 accepts four channels of 8-bit parallel data, performs 8B/10B encoding and decoding (with a bypass option), and sends the data over four differential signal pairs, while automatically compensating for data skew among the four channels of the VSC7216, and across multiple VSC7216s. Redundant I/O supports high reliability / high availability system architectures. Added features include analog and digital signal detect, receiver cable equalization, and JTAG boundary scan to facilitate chip-level and board-level testing. The JTAG port is compliant with IEEE Standard 1149.1-1990. "The VSC7216 is the easiest way to move high-speed parallel data from point A to point B," stated Fred Weniger, Vitesse product marketing manager. "The VSC7216 provides a compact and robust replacement for an 8Gb/s parallel bus, or for four separate Gigabit Ethernet or Fibre Channel transceivers. This third generation device contains logic for synchronization and deskewing plus other features our imitators haven't been able to copy," continued Weniger. The VSC7216 eliminates the cumbersome task of designing parallel bus architectures for network switches, routers, hubs, I/O modules and other equipment with high-bandwidth interconnection requirements. Compared to parallel interconnect schemes, the VSC7216 offers lower component count and circuit complexity, uses less board space and power, and allows greater flexibility for the system designer. The VSC7216 provides a serialized, duplex aggregate data transfer rate of over 8Gb/s over four channels and is easily configurable to either four 8-bit channels or a single 32-bit channel. A scaleable interconnect of arbitrarily high data width or throughput is easily achieved by synchronizing multiple VSC7216 ICs in parallel. Backplane and bus architectures must either widen or increase in clock frequency to accommodate the demands for increased bandwidth. By serializing data, the VSC7216 reduces the complexity and cost of high bandwidth parallel bus and backplane architectures while reducing data skew and interference associated with parallel implementations. A single VSC7216 has the same data throughput as 160 signals clocked at 50Mb/s. The VSC7216 consists of quad 8-bit Gigabit Ethernet/Fibre Channel compliant transceivers that can operate as either a fully synchronous 32-bit interface or as four independent transceivers. Each 8-bit channel can operate at a maximum data rate of 127MHz bits (1.016Gb/s) for an unencoded duplex aggregate data transfer rate of 8.128Gb/s. Each of the VSC7216's transceivers includes 8B/10B encoding-decoding with a bypass option, resulting in a total data channel throughput of 10Gb/s over four duplex channels. The VSC7216 also features bit, character, channel, and word synchronization, as well as synchronization among multiple VSC7216s. Elastic buffers are provided on the transmitter sides and the receiver sides of all four channels to realign the recovered data to a common clock and to the other channels. This unique feature automatically compensates for up to +/-2 bit periods of channel-to-channel skew, thereby eliminating problems due to mismatches in trace or cable length. No external synchronization or buffering components are required. The VSC7216 operates off a single +3.3V supply and dissipates 3.0 W. It is available in an industry standard 256-pin 27mm BGA package. Sampling is available now with pricing for 10,000 units at $38.
