Abstract
A DPWM () has a delay lock loop () which receives an input clock signal and provides an out-of-phase delayed clock at the output of each of eight delay cells (). A multiplexer () selects one of the delay cell outputs at any one time. This allows the DPWM () to have eight times the resolution which would otherwise be achieved with the same input clock. A programmable module () has a control block () which interfaces with external CPU and DSP hosts and transmits programmed parameters to finite state machine controllers (), each providing an independent output.
