Supply voltages VCC, VCCI, VOFFSET, VBIAS, and VRESET are all required for proper DMD operation. VSS must also be connected.
VOFFSET supply transients must fall within specified max voltages.
To prevent excess current, the supply voltage change |VCCI – VCC| must be less than specified limit.
To prevent excess current, the supply voltage change |VBIAS – VOFFSET| must be less than specified limit. Refer to Section 9 for additional information.
Tester conditions for VIH and VIL:
Frequency = 60 MHz. Maximum Rise Time = 2.5 ns at (20% to 80%)
Frequency = 60 MHz. Maximum Fall Time = 2.5 ns at (80% to 20%)
PWRDNZ input pin resets the SCP and disables the LVDS receivers. PWRDNZ input pin overrides SCPENZ input pin and tristates the SCPDO output pin.
The SCP clock is a gated clock. Duty cycle shall be 50% ± 10%. SCP parameter is related to the frequency of DCLK.
Refer to Figure 6-2.
SCP internal oscillator is specified to operate all SCP registers. For all SCP operations, DCLK is required.
Refer to Figure 6-3, Figure 6-4, and Figure 6-5.
Simultaneous exposure of the DMD to the maximum Section 6.4 for temperature and UV illumination reduces device lifetime.
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 the calculation in Section 7.6.
Long-term is defined as the average over the usable life.
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. See Section 7.7.
Short-term is the total cumulative time over the useful life of the device.
The locations of thermal test points TP2, TP3, TP4, and TP5 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.
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.
The average over time (including storage and operating) that the device is not in the 'elevated dew point temperature range'.
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.
The maximum optical power that can be incident on the DMD is limited by the maximum optical power density and the micromirror array temperature.
