    What is an EFT? Part 2

    In my last post , I discussed what an electrical fast transient (EFT) is at a high-level. For part two, let’s explore why EFTs matter and why they should be considered during your design process. Ultimately, EFTs matter for two key reasons: First, acceptable amounts of interference will vary greatly from application to application and could...

    Create an eye-opening experience with a 10G USB3 redriver

    Signal integrity, the measure of electrical signal quality, can be visualized by displaying a signal waveform on an oscilloscope. This visualization is commonly known as an eye diagram, and is generated by overlaying the waveform’s positive and negative bits. When superimposed, these bits produce an image that resembles an open eye, hence the...

    How the RS-232 transceiver’s regulated charge-pump circuitry works

    The RS-232 interface is popular in single-ended low-speed serial communications. The interface was originally designed to connect the serial port of a computer to peripheral devices. The Electronics Industry Alliance (EIA)-232 levels are defined as up to ±15V into a 5kΩ load. Thus, RS-232 transceivers need three supplies from the system...

    Emerging medical applications for optical heart rate sensor technology in wearables

    This is the third installment in a three-part series on optical heart rate sensors for biometric wearables. The first installment focused on how these sensor systems work and what you can measure with them. Part 2 shared the top 10 lessons learned from Valencell’s completion of more than 50 biometric wearable product development cycles. In...

    How to achieve network synchronization clocks with TI digital PLLs

    As current telecommunication networks move from legacy synchronous optical networking (SONET)/synchronous digital hierarchy (SDH) networks to Ethernet transport networks, more and more services are concurrently becoming time critical. For example, in financial markets, applying the Institute of Electrical and Electronic Engineers (IEEE) 1588 precision...

    What are the advantages of using JFET-input amplifiers in high-speed applications?

    As an introduction to this post, let me provide some background. Voltage-feedback amplifiers are sometimes categorized based on the type of transistors in the device: either bipolar, complementary metal-oxide semiconductor (CMOS) or junction field-effect transistor (JFET). A few amplifiers may even use a combination of these transistors to extract their...

    How sensor technology is evolving to meet cold chain needs

    With full compliance now in effect for the U.S. Food and Drug Administration’s (FDA) Sanitary Transportation Act, it’s a good time to provide an update on TI’s technology to help meet the evolving needs of cold chain, hazard analysis critical control point (HACCP) and good distribution practices (GDP) requirements. In a previous blog...

    How to calculate the power dissipation of high-speed RS-485 transceivers

    The RS-485 interface is widely used in industrial applications because of its robustness and long-distance communication capability. Since the RS-485 standard was first introduced to the market in 1998, electronic systems have increased in size and complexity. Many end equipments, such as motor drives, PLCs, and industrial PCs, now require high-speed...

    Improving IC reliability for harsh design environments

    It’s hard to believe that I’ve actually grown up with the integrated circuit (IC), which recently turned 50 years old (I pre-date that slightly … but hey, who’s counting). As a boy, I dreamed of Star Trek-like communicators a...

    Smart speakers don’t have to sound as small as they are

    Smart speakers are ingeniously helpful devices, providing weather reports, ordering food or playing a favorite song. As consumers find more ways to use virtual assistants, these devices are being added to more rooms, and the size of the device is shrinking to make them less conspicuous. Unfortunately, there is a direct relationship between speaker...
