ZLNB254
Dual DiSEqC™ Interface IC
SUMMARY
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. Packaged in a small footprint
DFN and only requiring two external components per channel the complete solution
is cost effective and requires minimal PCB space.
