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.
