Abstract
A simultaneous bi-directional transceiver is described. The transceiver comprises two circuits which are disposed at opposite ends of an interchip cable. In response to the application of digital data signals to these circuits, they generate a trilevel voltage at the ends of the interchip cable. Then, in each circuit, a first input to a differential amplifier is generated from the trilevel voltage by a level shifter comprising a first diode and a first constant current sink and a second input to the differential amplifier is derived from the digital data input signal applied to that circuit by a level shifter comprising a second diode and a second constant current source. Finally, the transceiver outputs are generated from the differential amplifier outputs.
