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

FEATURES
• Dual polarization and tone switch
• Temperature compensated polarization switches
• Reduced cost solution, only 2 external components
   per channel
• Multiplexer IC direct drive
• Tone and pol. outputs are TTL, CMOS, pin diode and
   IF amp capable
• Transient resistant inputs
• Includes receiver-off detector
• User adjustable filter centre frequency and
   bandwidth
• Low frequency and DiSEqC™ control signals
   rejection
• Eliminates many close tolerance discrete
   components
• Wide supply operating range
• Low quiescent current

APPLICATIONS
• Twin Universal LNB’s
• Quad Universal LNB’s
• Multi Feed Universal LNB’s
• LNB switch boxes
