(1) All voltages are referenced to common ground VSS. VBIAS, VCC, VOFFSET, and VRESET power supplies are all required for proper DMD operation. VSS must also be connected.
(2) VOFFSET supply transients must fall within specified max voltages.
(3) To prevent excess current, the supply voltage difference |VBIAS – VOFFSET| must be less than specified limit. See Power Supply Recommendations, GUID-BBD88DB5-2E1C-4253-B6FC-C4162A27DD06.html#DLPS1599748, and Table 9-1.
(4) To prevent excess current, the supply voltage difference |VBIAS – VRESET| must be less than specified limit. See Power Supply Recommendations, GUID-BBD88DB5-2E1C-4253-B6FC-C4162A27DD06.html#DLPS1599748, and Table 9-1.
(5) Low-speed interface is LPSDR and adheres to the Electrical Characteristics and AC/DC Operating Conditions table in JEDEC Standard No. 209B, “Low-Power Double Data Rate (LPDDR)” JESD209B.Tester Conditions for VIH and VIL.
  • Frequency = 60 MHz. Maximum Rise Time = 2.5 ns @ (20% – 80%)
  • Frequency = 60 MHz. Maximum Fall Time = 2.5 ns @ (80% – 20%)
(6) PWRDNZ input pin resets the SCP and disables the LVDS receivers. PWRDNZ input pin overrides SCPENZ input pin and tristates the SCPDO output pin.
(7) The SCP clock is a gated clock. Duty cycle must be 50% ± 10%. SCP parameter is related to the frequency of DCLK.
(11) Simultaneous exposure of the DMD to the maximum Recommended Operating Conditions for temperature and UV illumination reduces device lifetime.
(12) The array temperature cannot be measured directly and must be computed analytically from the temperature measured at test point 1 (TP1) shown in GUID-07E49ADF-BA45-491F-86FB-ADBE885C5B80.html#DLPS1599630 and the package thermal resistance using the Micromirror Array Temperature Calculation.
(13) Per #DLPS1591904, the maximum operational array temperature must be 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.
(14) Long-term is defined as the usable life of the device.
(15) Array temperatures beyond those specified as long-term are recommended for short-term conditions only (power-up). Short-term is defined as cumulative time over the usable life of the device and is less than 500 hours.
(16) Temperature delta is the highest difference between the ceramic test point 1 (TP1) and anywhere on the window edge as shown in GUID-07E49ADF-BA45-491F-86FB-ADBE885C5B80.html#DLPS1599630. The window test points TP2, TP3, TP4 and TP5 shown in GUID-07E49ADF-BA45-491F-86FB-ADBE885C5B80.html#DLPS1599630 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, use that point.
(17) DMD is qualified at the combination of the maximum temperature and maximum lumens specified. Operation of the DMD outside of these limits has not been tested.
(18) The average over time (including storage and operating) that the device is not in the ‘elevated dew point temperature range.
(19) The locations of thermal test points TP2, TP3, TP4 and TP5 in Figure 10 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.
(20) Limit the exposure to dew point temperatures in the elevated range during storage and operation to less than a total cumulative time of CTELR.
(21) The maximum marginal ray angle of the incoming illumination light at any point in the micromirror array, including Pond of Micromirrors (POM), cannot 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.
