Abstract
Embodiments of integrated circuits for use in a broadband tuner are described. In one embodiment, an integrated circuit includes a clock buffer configured to buffer a received clock signal and generate a buffered clock signal. Additionally, the integrated circuit includes a multiphase local oscillator core coupled to the clock buffer and configured to generate a plurality of oscillator signals in response to the buffered clock signal, each of the plurality of oscillator signals being mutually phase shifted. The integrated circuit may also include a plurality of output buffers, each configured to receive one of the plurality of oscillator signals and to produce an output signal suitable for use in a broadband tuner circuit in response to the one of the plurality of oscillator signals.
