(1) All voltages are referenced to common ground VSS. VDD, VDDI, and VCC2 power supplies are all required for proper DMD operation. VSS must also be connected.
(2) VCC2 supply transients must fall within specified max voltages.
(3) To prevent excess current, the supply voltage delta |VDDI – VDD| must be less than the specified limit. See the DMD Power Supply Requirements. 
(4) PWRDNZ input pin resets the SCP and disables the LVDS receivers. The PWRDNZ input pin overrides the SCPENZ input pin and tristates the SCPDO output pin.
(5) See LVDS clock timing requirements in Timing Requirements.
(6) See Figure 5-5 for the LVDS waveform requirements.
(7) Simultaneous exposure of the DMD to the maximum Recommend Operating Conditions for temperature and UV illumination reduces device lifetime.
(8) The array temperature cannot be measured directly and must be computed analytically from the temperature measured at test point 1 (TP1), shown in Figure 6-1 using the Micromirror Array Temperature Calculation.
(9) Long-term is defined as the usable life of the device.
(10) Per Figure 5-1, the maximum operational array temperature is derated based on the micromirror landed duty cycle that the DMD experiences in the end application. See Micromirror Landed-on/Landed-off Duty Cycle for a definition of micromirror landed duty cycle.
(11) Short-term is the total cumulative time over the useful life of the device.
(12) The average over time (including storage and operating) that the device is not in the elevated dew point temperature range.
(13) Exposure to dew point temperatures in the elevated range during storage and operation is limited to less than a total cumulative time of CTELR.
(14) Applies to region defined in Figure 5-2
(15) The active area of the DMD is surrounded by an aperture on the inside of the DMD window surface that masks structures of the DMD device assembly from normal view.  The aperture is sized to anticipate several optical conditions. Overfill light illuminating the area outside the active array can scatter and create adverse effects to the performance of an end application using the DMD. Minimizing the light flux incident outside the active array is a design requirement of the illumination optical system. Depending on the particular optical architecture and assembly tolerances of the optical system, the amount of overfill light on the outside of the active array may cause system performance degradation.
(17) The maximum allowable optical power incident on the DMD is limited by the maximum optical power density for each wavelength range specified and the micromirror array temperature (TARRAY).
