independent LNB down-converters in satellite
antenna dishes. It provides good performance
with a minimum of external components.
The STEVAL-CBL004V1 includes all the functions
needed for the design of dual tuner STBs, with
supplying/interfacing functions that are compliant
with the international standards.
It features an I²C bus interface and, thanks to the
fully integrated step-up DC-DC converter, it works
