Separate scale DACs allow independent scaling of both Fast output switching speeds with pulse rise/fall times of threshold and color DAC output values to control the projector 1.5ns for crisp pixels brightness or provide simple Automatic Power Calibration Intersil laser voltage sampler function with integrated (APC) for laser based systems. Pixel data information is dynamic power optimization controller to dramatically transferred through the LDD s high speed 10-bit parallel video minimize system power interface. There are two parallel interface modes to allow Flexible data order supports different RGB LD three or four color pixel data to be entered efficiently. Pixel opto-mechanical placement data employs a double data rate scheme, allowing video data to be transferred using both edges of the clock. Blanking time power reduction to reduce LDD current consumption Applications Programmable multi-pulse Return to Zero (RTZ) function to RGB scanning laser projection system provide maximum flexibility Laser-based projectors Single 3.3V supply and 1.8V video interface compatible for low power systems Generic laser-based applications requiring multiple independently controlled lasers or a single high current 3-wire SPI interface driver Operating temperature range: -40C to +125C AEC-Q100 qualified 12V DCDC Reg4 FB FB4 3.3/2.5/1.8V DCDC Reg3 FB = FERRITE BEAD FB3 TEST POINT DCDC Reg2 VSL FB2 MON VDD DAC 3.3V FB VDD A1 VDD A2 DPM4 DCDC VDD Reg1 DPM3 DPM2 VSS LD1 LD2 LD3 LD4 DPM1 FB1 ISL78365 SEN IOUT1 SCLK MCU IOUT2 SDIO IOUT3 IOUT4 EXTERNAL EVENT 1 L EN EXTERNAL EVENT 2 RSET LD1 to 4 can be in any order 10 EXAMPLES D 9..0 PGND CLK LD1 LD2 LD3 LD4 VIDEO PGND SYNC B ASIC or MEMS R G G DATA CONTROLLER PGND B G G R RGB(24) RTZ PGND G R G B LOWP EPAD R R G B FIGURE 1.
