Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1)
All grounds on board are tied together to prevent voltage differences of more than 0.2V maximum for any combination of ground signals.
(2)
At DVDD values lower than 1.65V, the PLL does not function. Refer to the Maximum TLV320AIC3254 Clock Frequencies table in the
TLV320AIC3254 Application Reference Guide (SLAA408) for details on maximum clock frequencies.
