ABSTRACT:
An interface for current mode to Manchester encoded serial signals includes symmetric positive
egative doublet pulse generation. The doublet pulse generator provides a pulse duration held constant by feedback and a voltage/current reference and a minimal gap between the positive and negative polarity pulses by using the same signal to both turn off the positive pulse driver and turn on the negative pulse driver. Fault detection by sensing of asymmetry in received pulse uses a comparator with both high and low threshold input devices to provide minor asymmetry tolerance.
