FT2232H - synchronous fifo read and flow control by RD#

<< < (2/2)

FTDI Community:
Hello,

The data being clocked out of the FT2232H will be at 60Mhz, so a device clocked at 22Mhz would not be able to control this byte by byte. As long as you account for the clock mismatch in your buffering solution you should be able to use the RD# signal to pause the datastream whilst the target device reads from the buffer. I would suggest buying a development module to test your design.

Best Regards,
