LNBH24LQTR Description

LNBH24LQTR developed by STMicroelectronics is a type of dual LNBS supply and control IC with the step-up and I2C interface. It, assembled in QFN 5x5 ePAD, is specifically designed for analog and digital DUAL satellite receivers/Sat-TV, Sat-PC cards. It is able to provide the 13 / 18 V power supply and the 22 kHz tone signaling for two independent LNB down-converters in the antenna dishes and/or multi-switch box. A dual tuner STBs complete solution can be offered together with the extremely low component count, and low power dissipation together with a simple design and I2C standard interfacing.
