ABSTRACT:
The present invention relates to a system for communicating between two integrated circuits (ICs) or within an IC. The ICs are either on the same circuit boards or on different circuit boards with a common backplane. A first integrated circuit has transmitter circuit that generates frequency shift keying signals using digital data and a second integrated circuit has a receiver circuit for recovering the digital data from the frequency shift keying signals.
