DUAL POLARISATION SWITCH TWIN LNB
MULTIPLEX CONTROLLER
ISSUE 1- JANUARY 2001
DEVICE DESCRIPTION
The ZLNB101 dual polarisation switch
controller is one of a wide range of satellite
receiver LNB support circuits. It features two
completely independent channels, each
providing two logic outputs under the
control of a voltage sensitive input. It is
intended for use in Twin LNB designs,
replacing many dIscrete components to save
both manufacturing cost and PCB size whilst
improving reliability.
The two inputs of the ZLNB101 have a
nominal threshold of 14.5V. Their 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.
Normal and an inverted outputs are
provided for each input. All outputs can
source 15mA and sink 10mA making them
suitable to drive TTL and CMOS logic, pin
diodes and for IF-amp supply switching.

The ZLNB101 operates from a single supply
of between 5-12V. Its quiescent current is
typically only 4mA and this does not change
significantly with load or logic state. It is
available in either the standard SO8 or space
saving MSOP8 surface mount packages.
Device operating temperature is -40°C to
+85°C to suit a wide range of environmental
conditions.
