Abstract
Methods and apparatus for tuning are disclosed. One embodiment of the invention is directed to a tuner formed on a substrate. The tuner comprises a first die that receives an analog input signal and processes the analog input signal using analog processing circuitry to form analog output signals, and a second die that receives the analog output signals, converts the analog output signals to digital signals, and processes the digital signals to form output signals. Another embodiment of the invention is directed to a multi-chip module comprising a tuner adapted to process television signals of a plurality of types and of a plurality of standards to form output signals. A further embodiment of the invention is directed to a method that comprises receiving an analog signal from a signal source, filtering the analog signal to remove a portion of the analog signal, converting the analog signal to quadrature analog signals, converting the quadrature analog signals to digital signals, and filtering the digital signals to substantially isolate a channel of interest.
