摘要： A system can include a digital oversampler configured to oversample an input data stream; a rate generator configured to select a frequency that is not less than an expected frequency of the input data stream; a rate generator clock of the rate generator configured to output a clock signal that has the selected frequency; a sample receiver configured to receive at least one sample of the input data stream from the digital oversampler; a sample counter configured to be incremented by each received sample responsive to a determination that the sample receiver has received at least one sample of the input data stream from the digital oversampler; a sample rate converter configured to accumulate samples from the sample receiver at the rate of a “toothless” clock signal, wherein the sample counter is configured to be decremented by the “toothless” clock signal at the selected frequency responsive to a determination that the sample receiver has not received at least one sample of the input data stream from the digital oversampler; and an AND gate configured to pass the “toothless” clock signal to the sample rate converter responsive to a determination that an output of the sample counter is greater than zero.

摘要： A system and a technique for recovering data from an input data stream without synchronization of an input sampling circuit to the input data stream determines a count of incoming samples (or frames) without generating a signal that is frequency-locked to the input data stream. A first clock is generated comprising a frequency that is greater than or equal to an expected frequency of the input data stream. A sample count is incremented in response to a sample received in the input data stream, and is decremented in response to a second clock signal. The second clock is generated the first clock signal by passing the first clock signal if the sample count of the sample counter does not equal a predetermined sample count value and by blocking the first clock signal if the sample count equals the predetermined sample count value.
