Abstract
Composite video timing adjustments using digital resampling provides precise sub-pixel timing relative to a timing reference with a single video master clock. A digital resampler interpolates an input digital composite video signal as a function of a phase offset input which defines a fractional clock period of the video master clock derived from the timing reference. The sub-pixel offset digital composite video signal also may be adjusted by integer multiples of the video master clock period using a FIFO memory. The final timing adjusted digital composite video signal then is input to an analog reconstruction circuit to provide an output analog composite video signal that is precisely timed to the timing reference.
