7.3.9 Integrated Damping Resistor and Impedance Matching

The TXV0108-Q1 features a 10Ω integrated damping resistor to help minimize signal reflections on the rising and falling edges. If impedance matching with a 50Ω load is required, then a series resistor will be needed. Since the output impedance of the device will vary with the output voltage, (VCCB when DIR = High or VCCA when DIR = Low) Table 7-1 provides the recommended resistor values needed to impedance match a 50Ω load.
