(1) All power supply connections are required to operate the DMD: V_DD, V_DDA, V_OFFSET, V_BIAS, and V_RESET. All V_SS connections are required to operate the DMD.

(2) All voltage values are with respect to the V_SS ground pins.

(3) V_OFFSET supply transients must fall within specified max voltages.

(4) To prevent excess current, the supply voltage delta | V_DDA – V_DD | must be less than specified limit.

(5) To prevent excess current, the supply voltage delta | V_BIAS – V_OFFSET | must be less than specified limit.

(6) LVCMOS input pin is DMD_DEN_ARSTZ.

(7) See the low speed interface (LSIF) timing requirements in Timing Requirements.

(8) See the high speed serial interface (HSSI) timing requirements in Timing Requirements.

(9) Simultaneous exposure of the DMD to the maximum Recommended Operating Conditions for temperature and UV illumination reduces device lifetime.

(10) The array temperature cannot be measured directly and must be computed analytically from the temperature measured at test point (TP1) shown in Figure 7-1 and the package thermal resistance using the Micromirror Array Temperature Calculation.

(11) Per Figure 6-1, the maximum operational array temperature should be derated based on the micromirror landed duty cycle that the DMD experiences in the end application. Refer to Micromirror Landed-On/Landed-Off Duty Cycle for a definition of micromirror landed duty cycle.

(12) Long-term is defined as the usable life of the device.

(13) The maximum optical power that can be incident on the DMD is limited by the maximum optical power density and the micromirror array temperature

(14) Short-term is the total cumulative time over the useful life of the device.

(15) The locations of thermal test points TP2, TP3, TP4, and TP5 shown in Figure 7-1 are intended to measure the highest window edge
temperature. For most applications, the locations shown are representative of the highest window edge temperature. If a particular
application causes additional points on the window edge to be at a higher temperature, test points should be added to those locations.

(16) Temperature delta is the highest difference between the ceramic test point 1 (TP1) and anywhere on the window edge as shown in Figure 7-1. The window test points TP2, TP3, TP4, and TP5 shown in Figure 7-1 are intended to result in the worst case delta
temperature. If a particular application causes another point on the window edge to result in a larger delta in temperature, that point
should be used.

(17) The average over time (including storage and operating) that the device is not in the ‘elevated dew point temperature range'.

(18) Exposure to dew point temperatures in the elevated range during storage and operation should be limited to less than a total
cumulative time of CT_ELR.

(19) The maximum marginal ray angle of the incoming illumination light at any point in the micromirror array, including pond of micromirrors (POM), should not exceed 55 degrees from the normal to the device array plane. The device window aperture has not necessarily been designed to allow incoming light at higher maximum angles to pass to the micromirrors, and the device performance has not been tested nor qualified at angles exceeding this. Illumination light exceeding this angle outside the micromirror array (including POM) will contribute to thermal limitations described in this document, and may negatively affect lifetime.
