Abstract

A method of clocking a video processing circuit is performed by stalling a reference clock signal. The reference clock signal is stalled based on a stall signal from a clock-independent pulse width modulator. The stalled reference clock signal is used to produce a video clock signal for use by an image data processing circuit.
