TX<5:4> (bits 9:8) adjust the maximum current (Imax) of the transmit output stage. The gain of the output stage is
not changed. Typical values are shown in the table below:
Using these controls allows the performance of the output stage to be optimized under various conditions; for
example, current cant can be reduced if non-linear operation is required.
The nominal value recommended for TX<11:4> is 10101010.
An example of setting up the control register (address 4) for various systems is shown below:
