(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 DS90UB928Q-Q1V_DD33 and V_DDIO 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.

Supply Noise⁽³⁾				100	mV_P-P

(1) The DS90UB928Q-Q1V_DD33 and V_DDIO 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) V_DDIO should not exceed V_DD33 by more than 300 mV (V_DDIO < V_DD33 + 0.3 V).

(3) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC-coupled to the V_DD33 and V_DDIO 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 with 10 meter cable 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.
