DUAL POLARISATION SWITCH TWIN LNB

MULTIPLEX CONTROLLER

ZLNB101

ISSUE 1- JANUARY 2001

DEVICE DESCRIPTION

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.

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 manydIscretecomponents tosave

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

beachievedwiththeaddition of only asingle

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.
