| www..com Chrontel CH7026 Brief Datasheet CH7026 TV/VGA Encoder Features * TV encoder targets for handheld device, surveillance camera and automobile market. General Description The CH7026 is a semiconductor device targeting for handheld market, surveillance camera and * Supports multiple output formats such as analog TV (NTSC and automobile multimedia system. This device PAL), VGA and HDTV ( 480p,576p,720p, 1080i). Sync signals accepts digital video signals through its 24-bit can be provided in separated or composite manner. input bus and generates NTSC, PAL, VGA or * Three on-chip 10-bit high speed DACs providing flexible output HDTV (480p, 576p, 720p and 1080i) video signal capabilities such as single, double or triple CVBS outputs, by its 10-bit DACs. In addition, CH7026 has an YPbPr output, RGB output and simultaneous CVBS and Sembedded 16-Mbit SDRAM to support the CPU video output. interface. * 90/180/270 degree image rotation and vertical or horizontal flip. * 16-Mbit SDRAM is used as a frame buffer for frame rate conversion. * * * * CH7026 has incorporated an advanced technology that can perform real-time video rotations and frame rate conversions for incoming video stream. Flexible up and down scaling. These complicated tasks are achieved by storing Programmable 24-bit/18-bit/16-bit/15-bit/12-bit/8-bit digital video data to the internal SDRAM and applying input interface supports various RGB (RGB888, RGB666, RGB565 and etc), YCbCr (4:4:4 YCbCr, ITU656) and 2x or 3x scaling process if required. CH7026 provides great multiplexed input. CPU interface is also supported. flexibility for accepting different video data Supports flexible input resolution up to 800x800 and 1024x680. formats including RGB and YCbCr (e.g. RGB565, RGB 666, RGB 888, ITU 656). Pixel by pixel brightness, contrast, hue and saturation adjustment for each output is supported. (For RGB output, only brightness and contrast adjustment is supported). * Pixel by pixel horizontal position adjustment and line by line vertical position adjustment. * Supports CGMS-A for analog TV and HDTV * TV/Monitor connection detection capability. DAC can be switched off based on detection result. * Programmable power management. * Flexible pixel clock frequency from graphics controller is supported. (2.3MHz -120MHz) * Flexible input clock from crystal or oscillator is supported. (2.3MHz - 64MHz) * Supports slave input clock mode only. * Fully programmable through serial port. The CH7026 is available in BGA or QFP package. * IO and SPC/SPD voltage supported is from 1.2V to 3.3V. * Offered in BGA or QFP package. Note: the above feature list is subject to change without notice.
