STEVAL-CBL007V1
Simple and inexpensive, it provides good
performance while minimizing the number of
external components required.
It includes all functions needed for LNB supply
and interfacing, and is compliant with international
standards. It includes an I²C bus interface and,
due to the fully integrated step-up DC-DC
converter, functions with a single input voltage
supply from 8 V to 15 V.
