ZLNB2001 - DUAL TONE and POLARITY SWITCH LNB MULTIPLEX CONTROLLER

Description

The ZLNB200X 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 Universal LNBs, replacing many discrete components to save both manufacturing cost and PCB size whilst improving reliability. The two polarisation control inputs of the ZLNB200X have a nominal threshold of 14.75V. The threshold is temperature compensated to minimise drift. Each features a low and stable input curr.
