FTDI FT2232H (USB UART) baud rates?


Anyone used one of the FT2232H chips from FTDI?


Specifically, how do you figure out the permissible baud rates?


The data sheet is kind of vague, and I have to pick something in the 1-3 MBaud range but need to know what my options are.




Answer



I had this problem too. FTDI considers it more a driver issue than a chip issue. Head over to the FTDI App Notes area and look at the "AN_120 Aliasing VCP Baud Rates" PDF appnote.
