ABSTRACT:
A bidirectional signal separation module includes a comparator having a first input node communicatively coupled to a bidirectional single-ended bus, a second input node communicatively coupled to a first voltage source, and an output node communicatively coupled to a unidirectional data transmission node; and a resistive network having a first node communicatively coupled to the second voltage source, a second node communicatively coupled to the bidirectional single-ended bus, a third node communicatively coupled to ground, and a fourth node communicatively coupled to an electronic switch. The electronic switch is configured to alternately couple the fourth node of the resistive network to the second voltage source or ground according to a voltage level on a unidirectional data receiving node.
