4.3.1.5. Oversampler (RX)

The Oversampler (RX) extracts data from the oversampled incoming data stream when the detected clock frequency band is below the transceiver minimum link rate.

The oversampling factor is fixed at 5 and you can program the data width to support different number of symbols. The supported data width is 20 bit for 2 symbols per clock and 40 bits for 4 symbols per clock. The extracted bit will be accompanied by data valid pulse which asserts every 5 clock cycles.
