AUDIO: MSP4440K
The MSP4440K family of single-chip Multistandard Sound Processors
covers the sound processing of all analog TV-Standards worldwide, as
well as the NICAM digital sound standards and FM stereo radio. The full
TV sound processing, starting with analog sound IF signal-in, down to
processed analog AF-out (baseband audio), is performed on a single chip.
With its extended number of inputs and outputs, the MSP4440K can
handle all audio signals in modern LCD, PDP, or CRT TVs. Even additional
signals from Digital TV decoders are included in the MSP4440K's single
chip TV Audio concept.
The MSP4440K has an internal 40ms (stereo) audio delay line. Complex
video processing delays the picture by several video frames. To avoid
mismatch between sound and a speaker's lip movement, the audio has to
be delayed accordingly (lip sync).
The MSP4440K built-in stereo A/D converters offer a S/N ratio of 95dBA
typ. The multiple D/A converters with analog volume and 0.125dB steps
make use of the Micronas unique multibit Delta-Sigma technology,
offering a dynamic range of 95 dBA typically. The DSP processing is
performed at 48kHz sample rate, maintaining the full audio bandwidth of
20kHz.
