Description

Intended for analog and digital satellite STB receivers/SatTV, sets/PC cards, the LNBEH21 is a monolithic voltage regulator and interface IC, assembled in POWER SO-20, specifically designed to provide the 13/18V power supply and the 22KHz tone signalling to the LNB downconverter in the antenna or to the multiswitch box. The LNBEH21 supports both methods of communication currently used, 13/18V Control Word Communication Mode and DiSEqCTM communication. In this application field, it offers a complete solution with extremely low component count, low power dissipation together with simple design and I2CTM standard interfacing.
