Evaluation Tools

The EV8126DF-00A is an evaluation board for MP8126, which is LNB power supply and control voltage regulator. The board provides efficient, low noise power to the Satellite receiver’s RF LNB (Low Noise Block) converter.
The board accepts the supply voltage from 8V to 14V and the load current can be up to 550mA. The current limit can be adjustable with an external resistor.
The board provides a number of features described in the European EUTELSAT specification (DiSEqC) including: voltage selection of horizontal or vertical polarization directions of LNB and a selectable VOUT compensation for voltage drop on the long coaxial cable. In accordance with DiSEqC standard, the part can detect 22 kHz signal and output it with the builtin amplitudes and rise/fall times.
