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. 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.
