ADJD-J823中文资料Color Management Controller with Integrated RGB Photosensor数据手册Broadcom规格书

描述 Description

The ADJD-J823 is a CMOS mixed-signal IC with integrated RGB photosensors designed to be the optical feedback device of an RGB LED-based backlighting system. A typical system consists of an array of red, green and blue (RGB) LEDs, LED drivers and the ADJD-J823. The device samples the light output from the RGB LED array, processes the color information and adjusts the light output from the RGB LEDs until the target color is achieved. To achieve this, the device integrates an RGB photosensor array, an analog-to-digital converter front-end, a color data processing logic core and a high-resolution 12-bit PWM output generator.
