Grass Valley SDI DA with Composite Analog Monitoring

Space-saving, modular platform for advanced signal processing.

The SDA-1142 from Grass Valley, a Belden Brand, is a reclocked serial digital video distribution amplifier which provides five reclocked outputs and four composite analog video monitoring outputs.
It provides automatic equalization for up to 375 meters (1,230 ft.) of cable (Belden 1694A) with signal presence detection, remote reporting and offers reclocking — providing an additional level of signal integrity in long cable length applications.
The SDA-1142 supports serial digital video (SMPTE 259M) at 270 Mb/s.

SDA-1142 Features

  • SDI isolated input
  • 5 reclocked SDI outputs
  • 4 NTSC/PAL monitoring outputs
  • Supports 525/625-line format
  • 375m (1,230 ft.) automatic cable equalization
  • Status LED and remote reporting
