Abstract
A universal tuning module may include an oscillator, a first tuner configured to process a first television signal, a second tuner configured to process a second television signal, a first switch configured to pass its input containing information associated with an output of the oscillator to said first tuner, and a second switch configured to pass its input containing information associated with the output of the oscillator to the second tuner.
Claims26
An integrated circuit chip comprising:
- a phase-lock-loop (PLL) circuit configured to generate a clock signal;
- and
- a universal tuning system configured to receive a first television signal in a first signal path, a second television signal in a second signal path and said clock signal, wherein said universal tuning system comprises a first pair of mixers arranged in parallel and configured to mix a first frequency of said second television signal with a second frequency associated with said clock signal, and a pair of first filters arranged in parallel and downstream of said first pair of mixers.
