A CMOS differential transmitter and matched receiver apparatus and method for transmitting data. The system uses a CMOS bias network to create low voltage swings and optimize the voltage offsets to compensate for variations caused by the manufacturing process, and thereby increase data transmission rates to approximately 1 gigabit per second.

CMOS gigabit serial link differential transmitter and receiver

A means of converting low voltage CMOS logic levels operating with a 3.3 volts logic level to low voltage PECL logic levels operating with a 3.3 volts supply voltage and a 0.8 volts logic level. The circuit design is process insensitive, and the characteristics of the converter emulate the emitter follower outputs of ECL devices. The converter solves the signal ringing problems caused by open output conditions, and is less susceptible to electromagnetic interference.
