Intro to linear Hall effect sensors: Achieve contactless accurate position sensing
As consumers, we tend to overlook the technology that surrounds us today. Take, for instance, the trigger on your game controller. You’re playing as an archer, and the trigger mimics the action of using a bow and arrow. To draw the bow you depr...

Getting smart about stepper tuning
When I first heard about stepper tuning, I was really confused. How can a motor be out of tune? I started reminiscing about warming up for band concerts in high school, and wondered how system designers could do something similar for their motors. After watching a video from my colleague Matt Hein I learned these three things about stepper tuning...

Strengthening overvoltage protection for USB connectors in mobile applications
USB Type-C™ is changing how we connect and use our devices. With the availability of higher voltages at the USB Type-C connector through USB Power Delivery (USB PD), you need to include greater levels of protection in order to safeguard critical system components. One element to consider is overvoltage protection (OVP), which protects against...

The top 5 questions when using M-LVDS in backplane applications
The top 5 questions when using M-LVDS in backplane applications Multipoint low-voltage differential signaling (M-LVDS) is an established standard ( Telecommunication Industries Association/Electronic Industries Alliance [TIA/EIA]-899 ) that allows for high-speed communication between as many as 32 devices. M-LVDS can be used in a backplane configuration...

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...
