IQSDA35 Dual 3G/HD/SD DA with Reclocking Selectable Outputs

The IQSDA35 provides dual-channel distribution for HD-SDI 3 Gb/s, 1.5 Gb/s or 270 Mb/s SD-SDI signals with flexible routing of inputs to outputs. Input signal loss detection enables switching from a main to back-up feed automatically, providing emergency changeover functionality. Flexible output selection enables the IQSDA35 to be used either as a single-channel DA with 12 outputs, or in dual-channel mode with six outputs per input.

FEATURES

  • Single- or dual-channel 3 Gb/s SDI, HD-SDI and SD-SDI re-clocking distribution amplifier
  • Flexible selection of inputs allows single- or dual-channel operation
  • Input signal monitoring allows auto-changeover functionality to provide emergency switching
  • 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:
    • 3G-HD to SMPTE ST 424
    • HD-SDI to SMPTE ST 292
    • SD-SDI to SMPTE ST 259-C
  • Emergency input bypass option enables the SDI input signal to be passed through to SDI output 1 in the event of frame power failure or module removal
  • RollCall monitoring allows all signal paths to be managed
