Overview
The SD10DAC standard definition SDI to Analog Composite, Y/C, or Component is a broadcast quality converter designed to demanding quality specifications and utilizing the finest components available. The SD10DAC is useful for video monitoring, dubbing and desktop video applications. The SD10DAC accepts 10 bit SDI video supporting NTSC/PAL video standards by automatically detecting the format of the SDI stream input format and outputs 10 bit analog video in YPbPr, RGB, Y/C or Composite video according to user selection. The SD10DAC includes an LED indicating the presence of a locked SDI signal. The equalizer is optimized for 270 Mb/sec with excellent return loss (>15dB). The deserializer converts 525 or 625 SDI (SMPTE 259M-C) with EDH (Error detection and handling), NRZI-to-NRZ decoding and descrambling. The video encoder features high quality 10 bit DAC’s with super sub-alias filters with extended luminance frequency response providing studio quality video playback in PAL or NTSC with or without pedestal.
