  • Publication number: 20170126462
    Abstract: A digital code recovery circuit includes a data transmitter that outputs either input data or a preamble code as transmitter data. A radio frequency interconnect (RFI) transmitter modulates carrier signals based on the transmitter data and transmits the modulated carrier signals over a channel to an RFI receiver that demodulates the carrier signals to obtain recovered transmitter data. A calibration storage device stores preamble data and a calibration circuit receives the recovered transmitter data. If the recovered transmitter data originated from the preamble code, the calibration circuit determines a set of digital calibration adjustments from the recovered transmitter data and the preamble data. If the recovered transmitter data originated from the input data, the calibration circuit applies the set of digital calibration adjustments to the recovered transmitter data to obtain adjusted digital code and outputs the adjusted digital code.
