5. Installation ON OFF Output 75 Color Bars requires a valid Normal Operation no test signal is output SDI input Notes 1 The D4E is programmed for a 1 3 MHz chroma bandwidth when operating in composite video mode This provides the best quality video when encoding component digital video However with lower cost monitors it may be desirable to reduce the composite chroma bandwidth to 650 Khz to reduce the effects of cross color artifacts This option is available from AJA Video as a special order 2 The encoder D to A chip used in the D4E has an 8 bit input for component digital video and 10 bit D to0 A converters for the analog outputs This configuration is often described as an 8 bit signal path and 10 bit Quantization Due to the internal processing of the encoder chip it is advantageous to use 10 bit D to A converters at the output even though the input is 8 bits Specifications Typically DIOCE installation consists of the following 1 disconnect 5VDC from the convertor 2 configure the DIP switch for the desired equipment configuration and video formats 3 connect video equipment to the convertor BNCs 4 apply 5VDC power to the converter AJA power supply model DWP Item Specification Serial Input SMPTE 259M 270MB SDI SDI Cable Equalization 300 meter 8281 typical Outputs NTSC PAL 2 BNC Or NTSC PAL Y C 2 BNC Frequency Response 25dB to 5 5MHz Y
