US Patent 7352412 Miniaturized television tuner and television receiver including the same

A television tuner includes an IF output terminal for outputting an IF signal converted from a received television signal to an external source, and a channel-selection PLL circuit for converting a high voltage supplied from an external source to a tuning voltage and for supplying the tuning voltage to an internal tuned circuit. The IF output terminal and a high-voltage input terminal of the channel-selection PLL circuit are connected to each other via a first resistor.
