Claim Text:
1. An apparatus comprising: a first signal processing circuit configured to receive an input signal, wherein the first signal processing circuit is configured to acquire phase lock and/or track phase lock to the input signal for at least a first modulation scheme, wherein the first signal processing circuit is configured to sample a preamble portion of a waveform of the input signal at a first clock rate to acquire phase lock for a second modulation scheme; a second signal processing circuit configured to receive the input signal, wherein the second signal processing circuit is configured to at least track phase lock to the input signal for the second modulation scheme at a second clock rate, wherein the second clock rate is faster than the first clock rate; and a controller configured to receive an indication of which of at least the first modulation scheme or the second modulation scheme is applicable, to activate the first signal processing circuit for acquisition and tracking of the input signal in the first modulation scheme, to activate the first signal processing circuit for acquisition of the input signal in the second modulation scheme, and to activate the second signal processing circuit for tracking of the input signal in the second modulation scheme.
