Patent ID: 7647069

Claim:
A dual-mode communications device that is configured to operate in a first mode to process a first type of signal and in a second mode to process a second different type signal, the device comprising: an oscillator that provides a clock signal at a first sample frequency, a receiver that includes: a tuner that is configured to receive an incoming signal and provide therefrom an analog received signal, an analog-to-digital converter, operably coupled to the tuner and to the oscillator, that is configured to convert the analog received signal into a first stream of digital samples at the first sample frequency, a receiver controller that is configured to determine whether the incoming signal is of the first type or the second type and to provide a receiver control signal indicative of the type of the incoming signal, and a receiver sample rate converter operably coupled to the analog-to-digital converter and the receiver controller, wherein, in the first mode, the device is configured to bypass the receiver sample rate converter responsive to the receiver control signal indicating that the incoming signal is of the first type, and, in the second mode, the device is configured to enable the receiver sample rate converter to convert the digital samples at the first sample frequency to a second stream of digital samples at a second sample frequency responsive to the receiver control signal indicating that the incoming signal is of the second type.
