A 1.5 GBaud/sec Serial Link Monolithic Chip Set

A 1.5 GBaud/s serial data link comprised of a 2-chip set capable of transporting up to 21 parallel bits was successfully fabricated using a 25 GHz peak ft silicon bipolar process. This link features a new encoding scheme which allows DC balance in the serial stream, as well as an internally generated clock which phase locks to the user´s clock at the transmitter, and full clock recovery and data retiming at the receiver. In addition, a controller integrated with the link handles handshaking at start up for full duplex operation.
