18.104.22.168. TX Oversampler
There are three possible oversampling factors: 3, 4, and 5. The oversampler assumes that the input word is only valid for the number of clock cycles defined by the oversampling factor. The oversampler is enabled when the outgoing data stream is determined to be below the TX transceiver minimum data rate. The oversampler then reads the DCFIFO once every number of clock cycles determined by the oversampling factor.
