Abstract
Devices, systems, methods, and other embodiments associated with clocking a radio frequency channel are described. In one embodiment, an apparatus includes a wobble channel logic configured to at least partially decode a digital wobble signal and configured to control a time base generator to generate a clock signal that is synchronized to wobble data. The apparatus further includes scaling logic to scale the clock signal to produce a scaled clock signal, and radio frequency channel logic configured to at least partially decode a digital radio frequency signal. The radio frequency channel logic is configured to be clocked by the clock signal and the wobble channel logic is configured to be clocked by the scaled clock signal.
