Abstract: Aspects of the disclosure provide a receiver for receiving data over a wired communication channel. The receiver includes an analog front end circuit, a pulse generation circuit and a voltage-controlled oscillator (VCO). The analog front end circuit receives an analog signal carrying data over the wired communication channel, and outputs a data signal with data bit transitions between voltage levels.

Output of the determined neural network is post-processed as post-processed data. The post-processed data is compared to a known value range associated with the post-processed data to determine if the post-processed data satisfies a desired output result.
