Video and VGA Scan Converter Solution (AL251A-EVB-A0)
Key Specifications
The solution accepts VGA analog signals or analog video signals. It converts the analog VGA signal into NTSC/PAL S-video and composite video (CVBS), or analog RGB for SCART application. Additional bypass VGA output could be added via the video buffer. This implementation can display at both the monitor and TV simultaneously. Besides, it accepts NTSC/PAL S-video or composite video (CVBS) and converts into VGA analog signal output or 16-bit digital RGB/YUV output.
