STEVAL-CBL004V1 is a power supply demonstration board for LNB based on the LNBH24. It provides a complete interface between LNBs and I2C bus, built-in DC-DC converter for single 12V supply operation, high efficiency, compliance with main satellite receiver output voltage specifications, bidirectional DiSEqC™ 2.0 support, overload and overtemperature protection, and diagnostic feedback through I2C bits.
The STEVAL-CBL004V1 is a power supply demonstration board designed for Low Noise Block (LNB) converters, specifically based on the LNBH24 dual LNB supply and control IC. It serves as an integrated solution for supplying and interfacing two independent LNB down-converters in satellite antenna dishes, suitable for designing dual tuner Set-Top Boxes (STBs).
