This means TX clock source = TX clock pin and RX clock source = RX clock
pin. But you seem to want something else:

In that case I suggest you use the DPLL to recover your RX clock. But then
you need to (1) use NRZI encoding and (2) set the baud rate generator
frequency to 32 times the data rate:

--speed 38400 --nrzi 1 --clocks 0x78

So, the DPLL is used as the source for both RX clock and TX clock.
