5.4 Recommended Operating Conditions

Over operating free-air temperature range and supply voltages (unless otherwise noted). The functional performance of the device specified in this data sheet is achieved when operating the device within the limits defined by the Recommended Operating Conditions. No level of performance is implied when operating the device above or below the Recommended Operating Conditions limits.

(1) The following power supplies are all required to operate the DMD: V_DD, V_DDI, 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_OFFSETsupply transients must fall within specified max voltages.

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

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

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

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

(8) Refer to the SubLVDS timing requirements in Section 5.8.

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

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

(11) Per Maximum Recommended Array Temperature—Derating Curve, 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) 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. The window test points TP2, TP3, TP4, and TP5 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) The average over time (including storage and operating) that the device is not in the ‘elevated dew point temperature range'.

(16) 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.

(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 (T_ARRAY).

(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.
