SDA-1142
SDI Distribution Amplifier with Composite Analog Monitoring

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.
