STMicroelectronics LNBH23 LNB Interface IC Datasheet
The LNBH23 is a monolithic voltage regulator and interface IC intended for analog and digital satellite receivers, sat-TV, and sat-PC cards. It is specifically designed to provide the 13/18 V power supply and the 22 kHz tone signalling to the LNB down-converter in the antenna dish or to the multi-switch box. The device offers a complete solution with an extremely low component count and simple I2C standard interfacing.
