The CH7026 is a semiconductor device targeting for handheld market, surveillance camera and automobile multimedia system. This device accepts digital video signals through its 24-bit input bus and generates NTSC, PAL, VGA or HDTV (480p, 576p, 720p and 1080i) video signal by its 10-bit DACs. In addition, CH7026 has an embedded 16-Mbit SDRAM to support the CPU interface.\nCH7026 has incorporated an advanced technology that can perform real-time video rotations and frame rate conversions for incoming video stream. These complicated tasks are achieved by storing video data to the internal SDRAM and applying scaling process if required. CH7026 provides great flexibility for accepting different video data formats including RGB and YcbCr (e.g. RGB565, RGB 666, RGB 888, ITU 656).\nThe CH7026 is available in BGA or QFP package.\n
