Description

The 4422 is a full featured broadcast quality 270Mb/s SDI to universal analog encoder. It is housed in an extremely compact and rugged aluminum case ideally suited to both studio and portable applications. The analog output is selectable to YUV & composite (CVBS), RGB & CVBS, RGBS, or YC and 2 CVBS via switches on the end of the unit. These switches also control the output of a built-in test pattern, vertical blanking information and blackburst output.
