ZLNB2012 - DUAL TONE AND POLARITY SWITCH LNB MULTIPLEX CONTROLLER

Description

The ZLNB2012 dual polarisation and tone switch controller is one of a wide range of satellite receiver LNB support circuits available from Zetex.

Features

  • two completely independent channels, each providing logic outputs to control LNB polarisation selection, local oscillator selection and downfeed disable. It is intended for use in Twin, Quad and multiple feed Universal LNBs, replacing many discrete components to save both manufacturing cost and PCB size whilst improving reliability. The two highly accurate polarisation control inputs of the ZLNB2012 have a nominal threshold of 14.25V and to meet the required demanding needs from some broadcaster.
