Product overview
Description
The STEVAL-CBL011V1 demonstration board implements a DC-DC converter based on ST’s LNBH26 device. It is used to power LNBs in dish antennas to receive satellite TV signals.
The LNBH26 is an integrated solution for supplying/interfacing satellite LNB modules in accordance with international standards.
This single device offers a complete solution for dual-tuner satellite receivers and provides good performance at low cost using a low external component count.
The LNBH26 demonstration board includes an I2C bus interface and a factory-trimmed internal 22 kHz tone generator which can be controlled through the DSQIN pin (TTL compatible). This allows immediate DiSEqC™ data encoding.
Thanks to a fully integrated step-up DC-DC converter, the STEVAL-CBL011V1 demonstration board can operate with a single input voltage supply source, ranging from 8 to 15 V.
