The TX sample submodule is a transmit oversampling block. It repeats each bit of the input word a given number of times and constructs the output words.
This submodule relies on the fact that the input data is only valid on 1/x of the clock cycles, where x is the oversampling factor. Both the input and output words are clocked from the same clock domain.
