Abstract: A multiple channel Digital Pulse Width Modulator (DPWM) can include a single delay locked loop with a delay line, the delay line producing a number of outputs. Circuitry can use a delay line mask to mask a portion of the delay line outputs to produce a modified outputs so as to prevent premature pulse width reset. Jitter tolerance look ahead circuits can prevent jitter from causing premature reset of pulse width modulated signals. The pulse width modulators can include multiple alternately used multiplexers so that the operation of the pulse width modulators is not affected by the load time of the multiplexers.
