(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) The DS90UB924-Q1 VDD33 and VDDIO voltages require a specific ramp rate during power up. The power supply ramp time must be less than 1.5 ms with a monotonic rise.

(1) The DS90UB924-Q1 VDD33 and VDDIO voltages require a specific ramp rate during power up. The power supply ramp time must be less than 1.5 ms with a monotonic rise.
(2) VDDIO must not exceed VDD33 by more than 300 mV (VDDIO < VDD33 + 0.3 V).
(3) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC-coupled to the VDD33 and VDDIO supplies with amplitude >100 mVp-p measured at the device VDD33 and VDDIO pins. Bit error rate testing of input to the Ser and output of the Des shows no error when the noise frequency on the Ser is less than 50 MHz. The Des on the other hand shows no error when the noise frequency is less than 50 MHz.
