METHOD AND DIGITAL CIRCUIT FOR RECOVERING A CLOCK AND DATA USING A DIGITAL FREQUENCY DETECTION
摘要
<p>In a particular embodiment, a digital circuit includes a frequency detection circuit operative to compare information related to transitions between sequential samples of a received signal. The frequency detection circuit is further operative to generate a control signal to reduce a sampling rate of the received signal in response to a predetermined number of the sequential samples having a same value. The digital circuit also includes a digital phase detector operative to provide the information related to the transitions between sequential samples to the frequency detection circuit.</p>
