Why Semtech’s New AVX ASIC Family is a Superior Solution for AV Extension

Posted by Gareth Heywood on 19 May 2020

In the world of Pro AV, point-to-point cable extension technologies are essential for transmitting AV content from point A to point B, where standard cabling just cannot go the distance. With the advent of HDMI, full bandwidth AV signals are sent in digital form at high data rates over shielded twisted pair (STP) cables, which typically max out at around 20 meters of reach. When carrying 4K video content, HDMI operates at up to six Gigabits per second (Gbps), and as data rate increases, so does the challenge of transmitting it over longer distances. Soon after HDMI transformed AV connectivity to digital, another technology was developed to extend these signals over standard copper networking infrastructure. This technology is called HDBaseT.

Introducing the LoRaWAN® & 5G Fact vs. Fiction Series

Posted by Remi Lorrain on 13 May 2020

We’re well into 2020, and the promise of 5G networking is continuing to lead conversations across the wireless industry. However, as 5G deployments increase, we also see a rise in alternative low power technologies to offer flexible, cost effective power and low bandwidth options for these so-called massive Internet of Things (IoT) deployments. In particular, market demand for solutions based on Semtech’s LoRa® devices and the LoRaWAN® protocol is continuing to increase, including those helping to combat the global COVID-19 outbreak. It has become clear that as 4G and 5G will target low latency and high throughput applications in the near future, LoRa and LoRaWAN-based applications will make up a larger portion of the massive IoT space, led by mobile operators, unlicensed spectrum operators and enterprises across private rollouts. The market is heading toward a Multi-Radio Access Network (Multi-RAN) strategy leveraging complementary standards, including 4G, 5G, LoRaWAN, and others such as Wi-Fi 6.

How SDVoE™ Enables Interoperability in Pro AV

Posted by Helgi Sigurdsson on 12 May 2020

All Software Defined Video over Ethernet (SDVoE™)-type AV distribution endpoints are interoperable, regardless of vendor or origin. But why are these endpoints interoperable? What is it that helps guarantee this interoperability?

Semtech and Society of Women Engineers: Community, Diversity and Inclusion

Posted by Isabel Stumfall on 06 May 2020

Just a few short weeks ago, I had the privilege of speaking at the Society of Women Engineers (SWE) collegiate section at California Polytechnic State University, San Luis Obispo (Cal Poly SLO). Having been an active SWE member for five years and the 2019-2020 Section President for the San Buenaventura professional section, I was beyond thrilled to have the opportunity to represent Semtech at an event for SWE. This was able to take place thanks to a company culture of community building and enthusiastic support from Semtech leadership. Semtech’s CEO has spoken previously, such as in a recent interview with Authority Magazine, on the importance of diversity, setting the tone for Semtech’s commitment to a diverse workforce. Diversity meets inclusion when each member of the team takes the Semtech Core Value of treating all with dignity and respect, and applies that to supporting a global team and a commitment to recruiting with diversity in mind.

Systems Integrators are Key to Successful IoT Deployments

Posted by Roelof Koopmans on 29 April 2020

Enterprises are increasingly looking for ways to digitize processes and businesses. This trend started with the adoption of the Internet more than 20 years ago. First, eCommerce drove this trend, and later, Application Service Provisioning (ASP). was one of the first companies to realize that large enterprises need customer relationship management (CRM) solutions for its mobile workforce that allow entering data remotely into one hosted instance instead of typical on-premise enterprise applications. With the emergence of larger Internet bandwidth, many new software solutions were provided from the Cloud, such as SAP and Microsoft Office applications. This digitization trend then extended to industrial environments with the strongly promoted vision of Industry 4.0. Enterprises realized that there is much to gain when combining the typical silos of IT and legacy OT (Operational Technology) with enormous potential to create more efficiency and quality in manufacturing processes.

Part One: OBD-II Systems & Protocols

Posted by Anindita Bhattacharya on 23 April 2020

Think about a situation when you ordered merchandise online and you were eagerly expecting this package. Each day you watched through your window for the delivery truck to arrive, but unfortunately, it ended up arriving later than expected. In such a case, you would have benefited from a tracking system via your phone or computer. Then, you could know exactly when your package would arrive. Or think about another situation, when your child is picked up from school by the after-school service provider and you wonder if he or she has reached the destination safely. If there was an option to track the vehicle through your phone during your child’s journey it would be very useful.

Your LoRaWAN® Security Questions, Answered

Posted by Olivier Seller on 23 April 2020

The LoRaWAN® protocol is especially optimized for low power, wide area networks (LPWANs). It supports secure, bi-directional communication for IoT applications which scale to connect millions of potential devices. As security is a fundamental need in all IoT applications, the LoRaWAN protocol was designed with security in mind, with authentication and encryption built into the specification itself. However, a secure network protocol is only one half of the equation. Deploying a LoRaWAN-based application requires correct implementation of the protocol and a close adherence to recommended practices.

TVS Peak Pulse Power: Higher is Better, Right?

Posted by Bill Russell on 15 April 2020

One of the most misunderstood ratings for transient voltage suppressor (TVS) diodes is peak pulse power (PPP). Many engineers will select surge protection components based primarily on rated peak pulse power and assume that their system will be well protected. After all, it seems logical to assume that a higher power rating means the device can absorb higher transient currents and therefore should be superior. While peak pulse power ratings may be considered in the selection process, the device should not be chosen solely on this parameter. To illustrate why, let us review the definition of TVS peak pulse power.
