STANDARD DBS DUAL CHANNEL VOLTAGE AND TO NE DETECTOR

Summary

The ZLNB2016 is a dual channel polarisation (voltage) and band select (tone) detector IC, primarily for satellite applications such

as Low Noise Blocks (LNBs) and satellite distribution systems. An optimised design provides a low supply current and a wide

operating voltage whilst increasing performance and reliability. The ZLNB2016 offers excellent interference rejection with

minimal application cost and packaged in the 3x3mm QFN it provides a very small solution.

Features

• Two polarisation voltage detectors

• Two robust, interference tolerant 22kHz tone detection

(without external signal filtering)

• “No Receiver” detect function for power saving and

isolation control

• Low quiescent supply current, 2mA typical

• Wide operating supply vo ltage 3V to 8V

• Low external component count minimises application

cost

• True and inverted outp uts to supp ort popular multiplexer

Pin Assignments

Application

• Twin Universal LNBs

• Quad Universal LNBs

• Multi Output LNBs

• Satellite Multi-Switches
