A communications device may include a receiver, a tunable clock signal generator, a digital camera, and a processor. The receiver may be configured to receive communications over an air interface using a plurality of frequency channels. The tunable clock signal generator may be configured to generate a tunable clock signal responsive to a tuning input. The digital camera may be configured to capture digital images and to operate responsive to the tunable clock signal. The processor may be coupled to the receiver, the tunable clock signal generator, and the digital camera. Moreover, the processor may be configured to determine at least one of the plurality of frequency channels over which communications are likely to be received and to generate the tuning input for the tunable clock signal generator responsive to determining the at least one of the plurality of frequency channels over which communications are likely to be received. Related methods are also discussed.
