(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) When AVDD is turned off, TI recommends switching off the input clock (or ensuring the voltage on CLKP, CLKM is less than |0.3 V|). This configuration prevents the ESD protection diodes at the clock input pins from turning on.
