*: The digital link power DVDD-IO must be lower than the digital core power DVDD.
**: The standard testing condition before shipping is AVDD = 5.0V unless specified. Customers designing with a different
AVDD should contact Realtek technical support representatives for special testing support.
9.1.2. Threshold Voltage
DVDD-IO= 1.5V±5%/3.3V±5%, DVDD= 3.3V±5%, Tambient=25°C, with 50pF external load.
