STEVAL-CBL007V1 Datasheet PDF - ST Microelectronics

●STEVAL-CBL007V1 is a LNB power supply demonstration board based on the LNBH23L DiSEqC 1.X compliant. The LNBH23L is a monolithic voltage regulator and interface IC, specifically designed to provide the 15V power supply and the 22KHz tone signalling to the LNB down converter in the antenna dish or to the multi switch box. An integrated solution for supplying/interfacing satellite LNB modules, simple and inexpensive, it provides good performance while minimizing the number of external components required. It has all the 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 8V to 15V.
