DUAL POLARISATION SWITCH TWIN LNB MULTIPLEX CONTROLLER ISSUE 1- JANUARY 2001 DEVICE DESCRIPTION The ZLNB101 dual polarisation switch controller is one of a wide range of satellite receiver LNB support circuits.
It features two completely independent channels, each providing two logic outputs under the control of a voltage sensitive input.
It is intended for use in Twin LNB designs, replacing many dIscrete components to save both manufacturing cost and PCB size whilst improving reliability.
The two inputs of the ZLNB101 have a nominal threshold of 14.
5V.
Their threshold is temperature compensated to minimise drift.
Each features a low and stable input current that enables transient protection...
