Abstract
A tri-level serial data stream and its inverted form are received and separated into data and clock for use with standard bi-level logic. The incoming tri-level signal and its inverted form are separately biased to permit a true differential comparison and signal detection. High common mode rejection of noise that is developed between a transmitter and receiver is thus provided.
