Abstract
Transceiver apparatus includes a transmitter circuit constructed with either emitter coupled logic (ECL) circuitry or programmable array logic circuitry, and a receiver circuit constructed with ECL circuitry. The transmitter circuit encodes a binary data signal received for transmission as a three-level modified duobinary encoded data signal and the receiver circuit decodes the received three-level encoded data signal to provide a binary data signal corresponding to the data signal received at the transmitter circuit for transmission. Both the transmitter and receiver circuits include features enabling transmitting and receiving high data-rate data signals.
