产品概述
描述
This product evaluation board implements a DC-DC converter based on the LNBH25L device used to power LNB inside dish antennas which receive satellite TV signals. The LNBH25L 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 LNBH25L evaluation board includes an I2C bus interface and the internal 22 kHz tone generator (factory trimmed) is controlled by the DSQIN pin (TTL compatible), permitting immediate DiSEqC™ data encoding. A fully integrated step-up DC-DC converter allows operation with a single input voltage supply source ranging from 8 V to 16 V.
