    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 and handheld medical scanners - as well as computers you could talk to that possessed seemingly endless...

    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...

    How much loading can an auto-polarity RS-485 bus support?

    The RS-485 interface is popular because of its robustness; the use of differential signaling effectively rejects common-mode noise on the bus. To make the communication work, the transceiver and receiver have to match the pins: A to A and B to B. In ...

    Gigabit xMII for 100BASE-T1: why are RGMII & SGMII important for 100 Mbps PHYs?

    Ethernet offers a more flexible networking technology for advanced driver assistance systems (ADAS), infotainment systems, body electronics and power trains; previous in-vehicle communication technologies required dedicated, special-purpose links and expensive cabling. The automotive amendments of the Institute for Electrical and Electronics Engineers...
