ABSTRACT:
Devices, systems, methods, and other embodiments associated with wobble channel clocking are described. In one embodiment, an apparatus implemented with a clock generator, a clock scaling logic, radio frequency channel logic, and wobble channel log. The clock generator generates a clocking signal. The clock scaling logic scales the clocking signal to produce a scaled clocking signal. The radio frequency channel logic at least partially decodes a digital radio frequency signal from an optical disk. The wobble channel logic at least partially decodes a digital wobble signal from the optical disk. Either the clocking signal or the scaled clocking signal is used to clock the radio frequency channel logic, and the other clocking signal or the scaled clocking signal is used to clock the wobble channel.
