7.3.3 Output Load Considerations

TI recommends following careful PCB layout practices to minimize signal distortion and ringing. Impedance matching techniques muat be implemented to reduce output oscillations and ensure signal integrity. Improper impedance matching can result in reflections that introduce overshoot and undershoot on signal transitions. Series termination resistors are recommended at the device outputs to match the total output impedance to the transmission line.

For example, given that the device output impedance is 21Ω (VCCA = 0.9 to 2V and VCCB = 3.3V), adding a series resistor value of 30Ω provides an effective source impedance close to 50Ω, matching a typical controlled-impedance trace or cable.
