CAMARILLO, Calif. -- Vitesse Semiconductor Corp. here today announced an optical interconnect chip for 10-gigabit-per-second applications that combines the transmitter and receiver functions on the same device.
The VSC7166 device from Vitesse is based on the emerging very short research (Very Short Reach) optical interconnect IC standard, a technology developed by Cisco Systems Inc. and endorsed by the Optical Internetworking Forum (OIF).
The VSC7166 is used to interface SONET-based OC-192 framers with parallel optical modules, allowing OEMs to connect networking equipment at distances at 300 meters or less. The device converts 16-bit, SONET-framed data to twelve 1.244-gigabit/sec. serial data, thereby enabling OEMs to reduce systems cost.
The user-selectable input termination resistance optimizes signal transfer, giving the designer increased signal margin. When used in conjunction with a VCSEL-based parallel optics module, the VSC7166 provides an innovative approach to short-reach data links, combining the benefits of SONET-framing with an optical layer based on Gigabit Ethernet standards.
The device provides forward error detection and is capable of recovering data transmission in the case of a down channel. The 1.8/2.5-volt device, which comes in a 256-pin BGA package, is $70 in 10,000-unit lots. Samples will be available in November, 2000.
