Abstract:

A tuning module tunes a dual frequency PLL synthesized tuner to a desired channel frequency. The dual frequency PLL synthesized tuner includes a first PLL and a second PLL. The tuning module receives a carrier-to-noise ratio ("CNR") for each of one or more signals output from the dual frequency PLL synthesized tuner. The tuning module then generates first PLL parameters and second PLL parameters based on the CNRs and the desired channel frequency. Finally, the tuning module programs the first PLL with the first PLL parameters and programs the second PLL with the second PLL parameters.
