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.
