NTSC or PAL output (respectively). In the absence of any SDI input the DB02 outputs a black and burst signal. NTSC or PAL output can be selected by a switch allowing the DB02 to be used as a black-burst generator. -

The positive video output is on pin 1 of the RJ-45 connector and the inverted video is on pin 2. In the absence of an SDI input the DB02 can act as a black-burst generator. A stable clock is used to drive the encoder and the output standard is selected by the NTSC/PAL switch (down for NTSC, up for PAL). -

3. DB02 Technical Details A simplified block diagram of the DB02 is shown in Figure 2. Figure 2 DB02 Block diagram. The +12VDC from the AC/DC power adaptor is filtered and protected from over-range or reverse polarity inputs. The 12VDC input is then regulated to provide clean power supplies for the module. -
