製品概要
概要
This evaluation board implements a DC-DC converter based on the LNBH26LS device. It is used to power LNBs inside dish antennas to receive satellite TV signals. The LNBH26LS is an integrated solution for supplying and interfacing satellite LNB modules in accordance with international standards. This simple and complete solution for dual tuner satellite receivers offers high performance at low cost and low external component count.
The LNBH26LS evaluation board includes an I²C bus interface and the internal 22 kHz tone generator which is factory trimmed and can be controlled by the DSQIN pin (TTL compatible), allowing immediate DiSEqC™ data encoding.
Thanks to a fully integrated step-up DC-DC converter, it functions with a single input voltage supply source ranging from 8 V to 16 V.
