The D4E SDI Encoder provides the lowest cost all-digital conversion of Component
Serial Digital (SDI) to analog NTSC or PAL Composite or Y/C (S Video). The D4E
is useful for monitoring, level and phase checking, dubbing, or desktop video
applications. The D4E automatically adapts to NTSC or PAL video standards and
outputs analog NTSC (525 line input) or PAL (625 line input).

The D4E encodes the full dynamic range of input component video—values below
black and above white are not clipped. In the NTSC mode, the 7.5 IRE pedestal can
be disabled by external DIP switch selection. Narrow/wide H/V blanking are also
configurable via DIP switches.
