STEVAL-CBL012V1

Dual LNB supply and control IC DiSEqC 2.0 compliant based on the LNBH26
  • active 活性

This product evaluation board implements a DC-DC converter based on the LNBH26 device used to power LNBs inside dish antennas which receive satellite TV signals. The LNBH26 is an integrated solution for supplying/interfacing satellite LNB modules in accordance with international standards, offering a complete solution for dual-tuner satellite receivers and good performance at low cost using few external components. The LNBH26 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.
