LNBH23 Product details

Description

Intended for analog and digital satellite receivers/sat-TV, sat-PC cards, the LNBH23 is a monolithic voltage regulator and interface IC, assembled in PowerSSO-24 ePAD and QFN32 (5 x 5 mm.) ePAD, 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.

Features

Complete interface between LNB and I²C bus.
Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93% @ 0.75 A), with integrated NMOS.
Selectable output current limit by external resistor.
Compliant with main satellite receiver systems specifications.
New accurate built-in 22 kHz tone generator suits widely accepted standards (patent pending).
Fast oscillator start-up facilitates DiSEqC™ encoding.
Built-in 22 kHz tone detector sup.
