DESCRIPTION

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

compensation for voltage drop on the long

coaxial cable. In accordance with DiSEqC

standard, the part can detect 22kHz signal and

output it with the builtin amplitudes and rise/fall

times.
