ZLNB254 - A dual DiSEqC™ interface and tone
detector for satellite applications.
Description
The ZLNB254 is a dual
channel DiSEqC™ interface
for satellite Low Noise
Blocks (LNB’s) and
distribution systems.
Providing two accurate
DiSEqC™ detectors, the
ZLNB254 converts the
DiSEqC™ signals into logic
level representations
enabling reliable and easy
detection for a
microprocessor.
The ZLNB254 can also
detect standard tone signals
used in satellite equipment.
Packaged in a small footprint
DFN and only requiring two
external components per
channel, the complete
solution is cost effective and
takes minimal PCB space.

The Diodes advantage

The ZLNB254 provides superior reliability in DiSEqC™ de-coding
by helping to eliminate false detection. Due to the detector
simplicity the ZLNB254 allows the work load in the micro-controller
to be reduced, allowing the designer to use a simpler controller.
