STANDARD DBS DUAL CHANNEL VOLTAGE AND TONE 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)
⢠âNo Receiverâ detect function for power saving and
isolation control
⢠Low quiescent supply current, 2mA typical
⢠Wide operating supply voltage 3V to 8V
⢠Low external component count minimises application
cost
⢠True and inverted outputs to support popular multiplexer
