Computationally efficient design for broadcast satellite single wire and/or direct demod interface
Abstract:
A broadcast satellite single wire interface. Such an interface comprises a low noise block amplifier module having multiple outputs, a plurality of filter banks, each filter bank coupled to each of the outputs of the low noise block amplifier module in a respective fashion and comprising a plurality of filters, and a plurality of analog-to-digital (A/D) converters, each A/D converter coupled to a filter in the plurality of filters in the plurality of filter banks in a respective fashion, wherein the A/D converters directly sample incoming downconverted broadcast satellite signals and the sampled incoming downconverted broadcast signals are output on a single wire in a stacked output.
