ch7053a-利来app官网

the chrontel ch7053a is specifically designed for consumer electronics device and pc markets which multiple high definition content display formats are required. with its advanced video encoder, flexible scaling engine and easy-to-configure audio interface, the ch7053a satisfies manufactures’ products display requirements and reduce their costs of development and time-to-market.

high quality high-bandwidth uncompressed video like dvi and yprpb components or legacy vga analog display are supported by the device’s color format converter. the 3 high-performance, 10-bit dacs can be used for either hdtv display or vga output depending on manufactures’ products specification. the device is compliant with eia770-3 and smpte 274m/293m/296m standards and supports hdtv resolution for up to 1080p. the ch7053a has the ability to generate composite syncs if required by the rgb monitor.

the ch7053a’s 24-bit parallel bus accepts a wide range of input data formats from the graphic controller. the built-in video port supports 8/12/16/18/24-bit data interface as well as 80/86 mpu interface. the video format conversion module is capable of translating digital rgb-565, rgb-666, rgb-888 or ycrcb (itu-r 656, itu-r 601) signal to the dvi signal, combining with the audio stream. the input digital signal also can be transformed by the dacs for hdtv or vga analog outputs.

the ch7053a supports both spdif and 2-channel i²s digital audio input. its high fidelity audio decoder engine has the capability of sampling audio frequency for up to 192k/2ch. the spidf supports pcm encoded data and compressed audio including dolby digital and dts.

the ch7053a has an image enhancement function that can fine tune brightness, contrast, hue and saturation down to the pixel-level.
