特征

Support multiple output formats. Such as SDTV format (NTSC and PAL), HDTV format for 480p,576p,720p and 1080i, analog RGB output for VGA. Sync signals can be provided in separated or composite manner (Programmable composite sync generation).
 Three on-chip 10-bit high speed DACs providing flexible output capabilities. Such as single, double or triple CVBS outputs, YPbPr output, RGB output and simultaneous CVBS and S-video outputs.
 Internal embedded 16Mbits SDRAM is used as frame buffer. Supporting for frame rate conversion. 90/180/270 degree image rotation and vertical or horizontal flip functions are supported.
 Programmable 24-bit/18-bit/16-bit/15-bit/12-bit/8-bit digital input interface supports various RGB (RGB888,RGB666, RGB565 and etc), YCbCr (4:4:4 YCbCr,ITU656) and 2x or 3x multiplexed input. CPU/Memory interface are supported.

 Support for flexible input resolution is up to 800x800 and 1024x680. 320x240, 640x480, 960x720 are support.

 Bypass mode is supported.

 Flexible up and down scaling engine is embedded including de-flickering capability. Text enhancement is supported.
 Pixel by pixel brightness, contrast, hue and saturation adjustment for each kind of output are supported. For RGB output, only brightness and contrast adjustment are supported.
 Pixel by pixel horizontal position adjustment and line by line vertical position adjustment are supported.
 Fully programmable through serial port. IO and SPC/SPD voltage supported is from 1.2V to 3.3V.
 TV/Monitor connection detect capability.
 Programmable power management. DAC can be switched off based on detection result (Driver support is required).
 Flexible pixel clock frequency from graphics controller is supported (2.3MHz –120MHz). Flexible input clock from crystal or oscillator is supported (2.3MHz – 64MHz).
 Offered in QFP package.
