ZLNB2013 - DUAL TONE AND POLARITY SWITCH LNB MULTIPLEX CONTROLLER

Zetex Semiconductors

Datasheet Details

The ZLNB2013 dual polarization and tone switch controller is one of a wide range of satellite receiver LNB support circuits available from Zetex.

two completely independent channels, each providing logic outputs to control LNB polarization selection, local oscillator selection and down feed 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 polarization control inputs of the ZLNB2013 have a threshold voltage of 14.75V to meet the switching requirement of 14.0V to 15.5V. To minimize drift both.
