  • Ethernet Protection Methodology

    Ethernet ports are exposed to external transient events in the form of electrostatic discharge (ESD), electrical fast transient (EFT), lightning, and cable discharge events (CDE). External transient voltage suppressor (TVS) diodes are commonly used to protect the Ethernet PHY chips from these threats. However, we find that a lot of confusion exists on how to best connect the TVS diode for maximum effectiveness. Common wisdom would suggest connecting the diode near the RJ-45 connector, from each signal line to ground. In actuality, the TVS should be connected across the signal pair and located on the PHY side of the connector. In this blog, we will examine why.

  • LoRa® Everywhere: Changing the World and Enabling a Better Life

    The increasing deployment of Semtech’s LoRa® devices and the open LoRaWAN® protocol is a global phenomenon. Leading industry analyst IHS Markit predicts up to 43 percent of all low power wide area network (LPWAN)-based Internet of Things (IoT) applications are expected to be based on LoRa devices and/or LoRaWAN networks by 2023*. Today, estimates place the number of LoRa-based gateways deployed at over half a million, providing connectivity to support up to two billion potential end devices**. Additionally, it is estimated the total number of LoRa-based end nodes deployed reached 135 million at the beginning of 2020**, enabling a nearly endless number of innovative use cases.

  • Unveiling AVX, the ASIC for AV Extension

    For most of my career at Semtech, I’ve been responsible for SDI-based products and technology, often extolling the features and benefits of copper-based, long-reaching audio and video (AV) signals. While SDI product lines matured into a meaningful business for the Signal Integrity Products (SIP) group at Semtech, there has been significant investment and record growth in optical fiber transmission technology for enterprise computing and communications. Fiber connectivity is now the backbone of worldwide communications with SIP optical products at the heart of this fiber revolution.

  • LoRaWAN® Gateways Need Robust ESD and Overvoltage Protection

    Gateways featuring Semtech’s LoRa® devices often reside in electrically harsh industrial environments. As the centerpiece for a LoRaWAN® network, these gateways need to operate in the field for many years. The longevity of the network requires that gateways be immune to a range of transient threats the equipment may encounter over its lifetime. As such, gateway data ports need to be safeguarded from overvoltage transient threats, including electrostatic discharge (ESD), electrical fast transients (EFT) and lightning surge.

  • The LoRa Alliance® and Connected Farming Solutions at World Ag Expo 2020

    Every year, major stakeholders in the North American agricultural network meet at World Ag Expo, one of the continent’s largest annual agriculture events. This year, the event will take place February 11 – 13 in Tulare, one hour south of Fresno in the heart of California’s Central Valley, where farmers produce more than one fourth of all U.S. food and one fifth of all U.S. dairy products.

  • Transient Protection of RS-485 Buses in Industrial Applications

    Modern industrial networks rely on robust RS-485 communication links for long distance data transmission. These networks operate in harsh electromagnetic environments and must be capable of withstanding electrical overstress (EOS) events without damage. Semtech’s Protection Products Group application engineering team recently had the opportunity to work with Renesas Corporation engineers on a reference design for protecting Renesas’ fault-protected RS-485 transceivers, used in industrial applications.

  • New Kit for Easy PoC of LoRa®-based Asset Tracking Solutions

    Semtech’s LoRa® devices represent a leading technology for connecting proven applications in the Internet of Things (IoT) space. Among its most successful applications are those for logistics management and asset tracking. In order to allow enterprise customers and other companies such as system integrators to demonstrate the capabilities of LoRa-based sensors or LoRaWAN®-based asset tracking, Semtech has launched a new demonstration tool, the Asset Tracking Kit. This new kit allows companies to quickly gain firsthand experience and see the value IoT data can provide to its business digitalization and strategy. The goal of this kit is to accelerate the transformation of proof of concepts (PoCs) into business opportunities for partners in the LoRa ecosystem.
