SDI04-2 is a 1×4 distribution amplifier for 3G/HD/SD-SDI signals.

The input circuitry of this device permits the compensation of the losses of the coax cable that brings the incoming signal.

The compensation capability changes with the resolution of the signal and with the type of cable.

Outputs are reclocked to ensure low jitter and optimal rise-fall times. For HD or 3G standard the Belden 1694A coax cable is recommended.
