摘要： A wireless device achieves good performance using a crystal oscillator that is not compensated for temperature. The crystal oscillator provides a reference signal having a temperature dependent frequency error. A control unit estimates the frequency error (e.g., based on a received pilot) and provides a frequency error estimate. A clock generator generates a digital clock, which tracks chip timing, based on the reference signal and the frequency error estimate. A receiver frequency downconverts an input RF signal with a receive LO signal having the frequency error and provides an analog baseband signal. An ADC digitizes the analog baseband signal based on a sampling clock having the frequency error and provides ADC samples. A re-clocking circuit re-clocks the ADC samples based on a digital clock and provides data samples. A digital rotator frequency translates the data samples based on the frequency error estimate and provides frequency-translated samples centered near DC.

摘要： Devices and methods for tuning a tunable circuit based on a frequency of operation of the tunable circuit using a clockless frequency detector circuit are described. The clockless frequency detector uses a filter having a slope in its frequency response curve that includes a frequency range of operation of the tunable circuit. Frequency-based attenuation through the filter of an RF signal provided to the tunable circuit is used to provide an indication of the frequency of operation. The tunable circuit, including the clockless frequency detector, can be integrated within a same chip that is autonomously configurable based on the frequency of operation.

摘要： A mobile TV receiver device includes antennas and an integrated circuit 200 which receives RF signals from the antennas 400 and demodulates them. The integrated circuit has a processing path for I/Q demodulation, a processing path for low IF demodulation, and a switch 206 which determines which of the processing paths is used to generate an output. Thus, the integrated circuit 200 can be employed irrespective of which of the two processing standards is required for received mobile TV signals. The integrated circuit 200 is designed to reduce power consumption in the mobile device, for example by disabling sections of the integrated circuit when they are not in use.
