LNBH221 - DUAL LNB SUPPLY/CONTROLLER

STMicroelectronics

General Description

Intended for analog and digital DUAL Satellite STB receivers/SatTV, sets/PC cards, the LNBH221 is a voltage regulator and interface IC, assembled in POWER SO-36, specifically designed to provide the power 13/18V, and the 22KHz tone signalling for two independent LNB down converters or to a multiswit

Key Features

ARE THE SAME FOR BOTH.
