Description  - PDF Spec Sheet
Xintekvideo's Professional SDI to Analog Converter is a full resolution very high quality bridge from D1 serial video to NTSC or PAL analog composite, Y/C, and component video. Internally generated color bars can also be outputted.
The Model SDI-110 Converter accepts 270 Mbs D1 data and it outputs a composite color signal, a Y/C signal, Y, R-Y, B-Y signals, or Red, Blue, Green video. In addition it outputs a frequency equalized and re-clocked 270 Mbs digital data making it possible to extend the transmission range of the digital signal.
Unlike other low cost (as well as some high cost) digital to analog converters on the market that may claim 10-bit processing but are actually limited to 8-bit quantizing accuracy, the Model SDI-110 maintains full 10-bit quantizing accuracy from the input port to the digital-to-analog conversion process. Video is properly low pass filtered and high frequency compensated for a flat frequency response out to 5Mhz. It has full 75 Ohm driving capability at both its digital output and its analog outputs.
The SDI-110 has front panel controls to adjust output video level. It also provides means to boost video high frequencies to compensate for the roll-off of video displays. As much as 4dB of boost can be added to the luminance. High frequency compensation is performed digitally. High frequency details are digitally cored to reduce noise visibility prior to combining with the video luminance. Appropriate digital clipping of highlights and blacks is done in the digital domain when high frequency boost is applied.
The SDI-110 has internal independent level adjustments of all output signals. That permits setting any output to +/- 30% of standard levels.
The Model SDI-110 is fully self contained, housed in a professional rack mounted cabinet. Two converters can be installed in the same cabinet. For two converters in one cabinet, specify Model SDI-110D.
