Improved television tuning circuits are disclosed. An example tuning circuit includes a fraction-N frequency synthesizer facilitating fine tuning. This tuning circuit may be formed using relatively few independent oscillators. The tuning circuit lends itself to the formation of an tuning circuit on an integrated circuit substrate. As well, this tuning circuit may be used to form a dual tuner tuning circuit integrated on a single integrated circuit substrate.
