DUAL TONE AND POLARITY SWITCH  
LNB MULTIPLEX CONTROLLER  
DEVICE DESCRIPTION  
The ZLNB2006/09/10 group of dual polarisation and Universal LNB local oscillator selection is achieved by  
tone switch controller are part of a wide range of detection of a low level AC voltage superimposed on  
satellite receiver LNB support circuits available from the polarisation control voltage. To facilitate this  
Zetex. Each part features two completely independent function, the ZLNB2006/09/10 includes a separate tone  
channels, each providing logic outputs to control LNB detector for each channel. Full control of detector  
polarisation selection, local oscillator selection and the bandwidth and sensitivity is provided using two

Polarisation switch and tone detector outputs can  
The two polarisation control inputs of the

ZLNB2006/09/10 have a nominal threshold of 14.75V. TTL and CMOS logic, pin diodes and IF-amp supply  
switching.  
The threshold is temperature compensated to  
minimise drift. Each features a low and stable input  
current that enables transient protection to be  
achieved with the addition of only a single resistor per  
channel.  
The ZLNB2006/09/10 operates from a single supply  
which can be anything from 5-10V. Their quiescent  
current is typically only 6mA and this does not change  
significantly with load or logic state. They are available  
in the space saving QSOP16 or QSOP20 surface mount  
package.  
Multi Feed LNBs can be called to operate with one or  
more of their controlling receivers powered  
down/disconnected, with attendant cable mismatch  
problems. To ease design for this situation, each  
polarisation input of the ZLNB2009/10 has a second  
threshold set at 9.5V. An input voltage below this  
threshold indicates “receiver not present”, switching  
the relevant control channels high. This logic output  
can be used to disable the associated downfeed driver,  
eliminating any problems due to cable mismatch.
