DA4-3GSDI is a multirate one Input/four Output serial distribution amplifier. Input equalization provides compensation for 100m (3G-SDI)cable loss, while Outputs are reclocked and independently buffered.Front panel LEDs gives quick information about the device status:power, data rate and PLL lock. The unit has a built-in power supply and housed in a metal enclosure for long term reliability and tough environment operation. DA4-3GSDI supports Level A, Level B Dual Link(B-DL) and Level B Dual Stream (B-DS).
