ZLNB1001
DBS tone and polarity multiplex controller
Description
The ZLNB1001 multiplex controller is one of a wide range of satellite
receiver LNB and IF distribution support circuits available from Zetex.
It supports a single IF path providing logic outputs to select one of four
IF switch input channels, which typically using PIN diodes. It is
intended for use in multi-switch applications for selection and
distribution of universal LNB IF output signals, replacing many discrete
components including the voltage regulator to save both
manufacturing cost and PCB size whilst improving reliability.
The highly accurate control input of the ZLNB1001 has both voltage and tone control for the four
required states. The voltage threshold is nominally 14.5 V and to meet the demanding
requirements of some broadcasters it has a switching range of 14.0 V to 15 V. The threshold is
temperature compensated to minimize drift. This features a low and stable input current that
enables transient protection to be achieved with the addition of only a single resistor.

The outputs are configured to deliver a positive regulated voltage drive of 7 V when a desired
channel is selected, and 0V when de-selected.
