(1) The following power supplies are all required to operate the DMD: VDD, VDDI, VOFFSET, VBIAS, and VRESET. All VSS connections are also required.
(2)
Section 6.4 are applicable
after the DMD is installed in the final product.
(3) The functional performance of the device specified in this
data sheet is achieved when operating the device within the limits defined by
the
Section 6.4. No level
of performance is implied when operating the device above or below the
Section 6.4 limits.
(4) All voltage values are with respect to the ground pins (VSS).
(5) VOFFSET supply transients must fall within specified max voltages.
(6) To prevent excess current, the supply voltage delta |VDDI – VDD| must be less than specified limit.
(7) To prevent excess current, the supply voltage delta |VBIAS – VOFFSET| must be less than specified limit.
(8) To prevent excess current, the supply voltage delta |VBIAS – VRESET| must be less than specified limit.
(9) LS_CLK must run as specified to ensure internal DMD timing for reset waveform commands.
(10) Refer to the SubLVDS timing requirements in
Section 6.7.
(11) Simultaneous exposure of the DMD to the maximum
Section 6.4 for
temperature and UV illumination will reduce 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
Figure 7-1 and the Package Thermal Resistance using
Section 7.6.
(13) 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
Section 7.7 for a definition of micromirror landed duty cycle.
(14) Long-term is defined as the usable life of the device
(15) Short-term is the total cumulative time over the useful life of the device.
(16) 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, 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
temperature, that point should be used.
(17) Window temperature is the highest temperature on the window
edge shown in
Figure 7-1. The locations of thermal test points TP2, TP3, TP4, and TP5 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 be at a higher
temperature, that point should be used.
(18) The average over time (including storage and operating) that the device is not in the elevated dew point temperature range.
(19) Exposure to dew point temperatures in the elevated range during storage and operation should be limited to less than a total cumulative time of CTELR.
(20) 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.
