The DLPC200 is one of three components in the 0.55 XGA Chipset (see Figure 1). Proper function and operation of the DLP5500 requires that it be used in conjunction with the other components of the 0.55 XGA Chip-Set. Refer to the 0.55 XGA Chip-Set Data Sheet for further details (TI literature number DLPZ004). In DLP electronics solutions, image data is 100% digital from the DLPC200 input port to the image projected on to the display screen. The image stays in digital form and is never converted into an analog signal. The DLPC200 processes the digital input image and converts the data into a format needed by the DMD. The DMD then reflects light to the screen using binary pulse-width-modulation (PWM) for each pixel mirror. The DLPC200 interfaces with an LED driver via an SPI interface. It sends strobes to indicate when each of the red, green, blue or infrared LEDs should be enabled or disabled and command packets are used to control the brightness of the LEDs.
