Section 6.4 is applicable after the DMD is installed in the final product.

(2)

The functional performance of the device specified in this datasheet is achieved when operating the device within the limits defined by

Section 6.4. No level of performance is implied when operating the device above or below the Section 6.4 limits.

(3)

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

(4)

VOFFSET supply transients must fall within specified maximum voltages.

(5)

To prevent excess current, the supply voltage delta |VDDI – VDD| must be less than specified limit.

(6)

To prevent excess current, the supply voltage delta |VBIAS – VOFFSET| must be less than specified limit.

(7)

To prevent excess current, the supply voltage delta |VBIAS – VRESET| must be less than specified limit.

(8)

LS_CLK must run as specified to ensure internal DMD timing for reset waveform commands.

(9)

Refer to the SubLVDS timing requirements in Section 6.7.

(10) Simultaneous exposure of the DMD to the maximum limits in Section 6.4 for temperature and UV illumination will reduce device

lifetime.

(11) The array temperature cannot be measured directly and must be computed analytically from the temperature measured at test point 1

(TP1) shown in Figure 7-1 and the Package Thermal Resistance using Section 7.6.

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

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

(14) Temperature delta is the highest difference between the ceramic test point 1 (TP1) and anywhere on the window edge shown in Figure

7-1. The window test points TP2 and TP3 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 temperature, that point should be used.

(15) Window temperature is the highest temperature on the window edge shown in Figure 7-1. The locations of thermal test points TP2 and

TP3 in Figure 7-1 are intended to measure the highest window edge temperature. If a particular application causes another point on

the window edge to result in a higher temperature, that point should be used.

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

(17) Exposure to dew point temperatures in the elevated range during storage and operation should be limited to less than a total

(18) 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.

(19) The active area of the device 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 window aperture is sized to anticipate several optical operating conditions. Overfill light directly

illuminating the window aperture can create adverse imaging effects, and additional device heating leading to reduced device lifetime.

Direct incident illumination should be prevented from striking the DMD window aperture.

(20) Applies to the region in red in Figure 6-1, at the inside plane of the glass window where the physical aperture is located.
