Well, let's do some maths...

100 data points / second with 12 bits resolution.

Using RS232 means 10 bits to be sent serially per data byte, (one start - eight data - one stop bit). So for 100 data points, the speed is 2000 Bits/second (as you need to send two bytes for 12 bits) which is pretty low. The next faster standard baud rate is 2400 Baud. The SX can easily handle higher Baud rates than this. When you clock the SX at 50 MHz, 9600 Baud is still pretty slow (from the SX POV) but more than fast enough to handle your data throughput. So, I don't see the need for any additional hardware UART.
