Abstract
A clock recovery apparatus for generating a recovery clock from received data may include, but is not limited to, first and second oscillators. The first oscillator generates a first signal having a first frequency. The first signal synchronizes with the received data when the received data has a first level. The second oscillator is connected in series to the first oscillator. The second oscillator generates a second signal as the recovery clock when the first signal has a second level. The second signal has a second frequency. The second signal synchronizes with the first signal.
