DUAL TONE AND POLARITY SWITCH

LNB MULTIPLEX CONTROLLER

DEVICE DESCRIPTION

The ZLNB2006/09/10 group of dual polarisation and

tone switch controller are part of a wide range of

satellite receiver LNB support circuits available from

Zetex. Each part features two completely independent

channels, each providing logic outputs to control LNB

polarisation selection, local oscillator selection and the

ZLNB2009/10 also provides downfeed disable. They

are intended for use in Twin Universal and Quad LNBs,

replacing many discrete components to save both

manufacturing cost and PCB size whilst improving

reliability.

T he tw o polari sati on c ont r ol i nputs o f th e

ZLNB2006/09/10 have a nominal threshold of 14.75V.

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.

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.

FEATURES

ISSUE 1 - APRIL 2002

Dual polarisation switch

Temperature compensated polarisation switch

threshold

Transient resistant inputs

Includes Receiver-Off detector (ZLNB2009/10)

Dual tone switch

User adjustable filter centre frequency and

bandwidth

User adjustable tone switching delays

Tone and Pol outputs are TTL, CMOS, Pin diode

and IF amp capable

Universal LNB local oscillator selection is achieved by

detection of a low level AC voltage superimposed on

the polarisation control voltage. To facilitate this

function, the ZLNB2006/09/10 includes a separate tone

detector for each channel. Full control of detector

bandwidth and sensitivity is provided using two

external resistors and capacitors. In the ZLNB2006/9,

additional control of tone switch delays is provided to

assist with the rejection of low frequency control

signals intended for other systems.

Polarisation switch and tone detector outputs can

source and sink 10mA making them suitable to drive

TTL and CMOS logic, pin diodes and IF-amp supply

switching.

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.

APPLICATIONS

Wide supply operating range

Low quiescent current

Few external components

Eliminates many discrete components

Twin Universal LNB

Multi Feed Universal Lnb’s

Twin Universal IF switch boxes

LNB switch boxes
