Systems and methods for reducing digital interference of external signals

摘要

A mobile device may include a digital data driver and digital data receiver for communication of digital signals within the mobile device at a selected clock rate. The mobile device may also have a device external for the digital data driver and digital data receiver for communication of external signals, such as radio-frequency signals, to and from the mobile device. To avoid interference of frequency harmonics of a digital signal with such external signals, the digital data driver may be configured to control the digital signal based on the frequency of the external signals, such that interference of the external signal by spectral content of the digital signal is minimized, while maintaining the selected clock rate.

1. A system comprising:
a digital data driver for generating a digital signal for communication to a digital data receiver at a selected clock rate, the digital data driver configured to:
receive an indication of a frequency of an external signal associated with a device external to the digital data driver and the digital data receiver; andwhen generating the digital signal, control the digital signal based on the frequency such that interference of the external signal by spectral content of the digital signal is minimized, while maintaining the selected clock rate.
