Q: Is there any information on Tx driver strength available?
A: There are no guaranteed specifications on the strength of the Tx Drivers for the MAX14830. The Tx buffer has less current capability than the GPIO buffers, so it cannot drive a significant load. Test data shows and approximate rise time of 1.4ns and fall time of 1.1ns while the part is running at 3.6V and driving a high impedance, low capacitance load.
