STEVAL-CBL009V1

DiSEqC 1.X-compliant single LNB supply and control IC based on the LNBH25
  • active Active

The STEVAL-CBL009V1 demonstration board implements a DC-DC converter based on ST’s LNBH25 device. It is used to power LNBs in dish antennas to receive satellite TV signals.

It provides good performance at low cost using a low external component count, and includes all functions needed for supplying/interfacing LNB modules in accordance with international standards.

The device includes an I2C bus interface and, thanks to a fully integrated step-up DC-DC converter, it works with a single input voltage supply ranging from 8 V to 16 V.
