NPA Number 001 New Product Announcement ZLNB254 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. Dual DiSEqC™ or tone detector and interface IC Only requires 2 external components per channel Designed to US and standard DiSEqC™ specifications DiSEqC™ is a trademark of Eutlesat Detectors reject unwanted signals Wide supply voltage of 3V to 8V and a low current design Small footprint DFN package Circuit functions DiSEqC™ LNB’s DiSEqC™ peripheral equipment DiSEqC™ satellite distribution systems www.diodes.com NPA Number 001 New Product Announcement ZLNB254 Micro-controller ZLNB254 - A dual DiSEqC™ interface and tone detector for satellite applications.
