摘要： Video decoder systems in which both the analog-to-digital converter and the composite decoder are driven by the stable sample clock, such as a crystal source. The outputs of the composite decoder are provided to a source rate converter, having an output that is provided to a digital output formatter. The digital output formatter is driven by the output clock, which may be locked to the source clock if desired. The output clock is developed by a clock generator which may be one of several different types, including a fractional N synthesizer, a direct digital synthesizer or a puncture clock.

摘要： A method of separating a chroma data component from a video data stream includes determining a phase relationship between a color burst in digital video data samples of a composite video signal and a local clock signal which processes the digital video data samples. In response to determining the phase relationship, interpolation filtering is performed on the digital video data samples corresponding to first and second display lines to generate phase aligned video data samples. Adaptive filtering is then performed utilizing the phase aligned video data samples corresponding to the first and second display lines to separate the chroma component from the digital video data samples corresponding to the first display line.

摘要： A method and apparatus for reducing switching noise in a system-on-chip (SoC) integrated circuit including an analog to digital converter (ADC) provides for reduced noise in the ADC conversions. Sampling circuits of the ADC are operated by sampling clock signals and digital circuits and other noise-generating circuits such as power converters, are operated by digital circuit clock signals. Both sets of clock signals are derived from the same master clock by a clock generator circuit, but an offset is applied in the clock generator circuit to move the edges of the digital circuit clock signals away from critical sampling intervals corresponding to edges of the sampling clocks. In one embodiment, the offset is applied by a processor core that forms part of the digital circuits by setting a value in the clock generator, which the clock generator then loads into the divider after halting the clock to the digital circuits.
