AT2615 / 2617 are two timing controllers for analog LCD screens launched by CoreView Technology, which are used to control AUO's AV type and other TFT LCD modules. They include a horizontal frequency driver and a phase-locked loop (PLL) phase comparison circuit, and they support external clock modes that do not require a PLL circuit. Both chips are powered by a single 5.0V power supply, which can generate various timing control signals required for LCD source drivers and gate drivers.

        AT2615 / 2617 chip adopts TQFP-48 package (pin pitch 0.5mm), which is mainly used in automotive audio and video systems and video surveillance systems, and can also meet the display needs of other occasions.
