Abstract
A programmable pulse generator having a clock signal delay chain, multiplexer, and reduced voltage charge circuit. The clock delay chain comprises a plurality of propagated delays, coupled to the multiplexer. The multiplexer selects a particular clock delay signal from a plurality of delay chain taps. The multiplexer is driven by a tap select register coupled to a state machine. The state machine controls the programmable pulse output, encoding the data by varying the pulse width and delay between pulses. The delay of pulse outputs from the multiplexer are reduced by coupling a reduced voltage pre-charge circuit to the multiplexer.
