ABSTRACT:
A digital logic interface circuit makes use of a logic signal representative of a logic signaling level definition, to determine the logic swing amplitude of signals from a given source adopting the same logic signaling level definition. The digital logic interface circuit generates a threshold level from the logic swing amplitude thus determined, and compares digital logic input signals against the threshold level in order to discriminate different logic levels in the digital logic input signals. The comparison result is provided as digital interface output signals adopting a predetermined logic signaling level definition for use by subsequent system sections. Examples of such representative signals are the digital input logic signals themselves, clock signals or line encoded signals. Other examples can be mode control signals or NRZ signals.
