ABSTRACT:
An apparatus for transforming single ended signals into differential mode signals. A preferred embodiment comprises an inverter (for example, inverter505) and a pair of latches (for example, latches510and520). One latch has as its input an input signal to be converted and the other latch has as its input an inverse of the input signal. The latches maybe clocked by a differential mode clock and remove a timing mismatch between the input signal and its inverse that is incurred via the inverter. The latch outputs are then provided to a differential mode buffer to perform signal voltage and current compatibility transformations.
