DUAL TONE AND POLARITY SWITCH

LNB MULTIPLEX CONTROLLER

DEVICE DESCRIPTION

The ZLNB2012 dual polarisation and tone switch Universal LNB local oscillator selection is achieved by

controller is one of a wide range of satellite receiver detection of a low level AC voltage superimposed on

LNB support circuits available from Zetex. It features the polarisation control voltage. To facilitate this

two completely independent channels, each providing function, the ZLNB2012 includes a separate tone

logic outputs to control LNB polarisation selection, detector for each channel. Control of detector

local oscillator selection and downfeed disable. It is bandwidth and sensitivity is provided using an

Universal LNBs, replacing many discrete components tone detector has been designed give excellent

improving reliability.
