IQSDA34 Triple 3G/HD/SD DA with Reclocking

The IQSDA34 provides three inputs with four outputs per input for distribution of 1080p 3 Gb/s SDI, HD-SDI 1.5 Gb/s or 270 Mb/s SD-SDI signals in a double-width package. Its 70m 3G, 140m HD-SDI input equalization performance and non-reclocking distribution of wide-band signals makes it ideal for all current distribution applications.

FEATURES

  • Triple-channel intelligent 3G-SDI, HD-SDI and SD-SDI reclocking distribution amplifier
  • Equalizes up to 70m at 3 Gb/s, 140m at 1.5 Gb/s and 350m at 270 Mb/s when using Belden 1694A cable
  • Standards supported:
    • 1080p SDI to SMPTE ST 424
    • HD-SDI to SMPTE ST 292
    • SD-SDI to SMPTE ST 259-C
  • Switchable option to connect channels together producing 1 input to 12 outputs, or 2 inputs with 8 and 4 outputs
  • RollCall monitoring allows all signal paths to be managed
