Description
- STEVAL-CBL016V1, Single LNB supply and control IC DiSEqC 1.X compliant with EXTM based on the LNBH29 in a QFN16 (4x4). The evaluation board implements a DC-DC converter based on the LNBH29 device used to power LNB inside dish antennas which receive satellite TV signals. The LNBH29 is an integrated solution for supplying/interfacing satellite LNB modules in accordance with international standards, offering a complete solution for single-tuner satellite receivers and good performance at low cost using few external components. The LNBH29 evaluation board includes an I2C bus interface and is provided with the EXTM analog modulation input pin to be connected to an external 22 kHz DiSEqC tone source. The tone output waveform depends on the characteristics of the external signal provided by the EXTM pin
