Move High-Speed Data Across Long Distances
A solid proven coding scheme combined with low-EMI receiver-equalized transceivers provides a reliable data link at low cost.
Universal Miniature Transceivers Conquer Industrial Networks
In addition drastically reducing the footprint, modern transceivers reduce power consumption, increase noise immunity, and substantially increase upper data rates while offering programmable features that make them versatile for a wider range of system designs
Even Cheapskates Need Reliable I2C Isolation! 2
The discrete I2C isolator is among the most often considered isolators. This most stubborn, hard-to-die design continues to fascinate many engineers due to its simplicity. Circuit performance, however, changes with variations in temperature and supply, making re-designs inevitable.
Capacitive Isolated Gate Drivers Spin AC Induction Motors
Legacy designs of variable frequency drives (VFDs) used optocouplers or pulse transformers for isolation and mated them together with gate driver ICs. A more integrated approach, though, uses capacitive isolated gate drivers to provide higher performance while being smaller in solution size and lower in cost.
Integrated AISG Transceivers Simplify Basestation Designs

 

State-of-the art wireless networks must provide high-speed data services to support the data-intensive applications of smart phones. Infrastructure deployment, however, is still costly and occasionally presents the reason for inadequate coverage in some areas.

RS-485: How To Correct The Bus Signal Polarity Of Cross-Wired Data-Links
TI's Thomas Kugelstadt offers a number of technical fixes for RS-485 bus signal polarity correction (POLCOR) in industrial control systems. POLCOR used to be rare. Now, it results from any of a number of bad bus design practices in developing countries.
How Much On-Chip Transient Protection Is Enough?
TI's Thomas Kugelstadt explains the difference offered by integrated electrostatic discharge (ESD) electrical fast transient (EFT) protection on IC input pins and external protection against EFT pulse trains and surges. The latter is common in industrial control and requires external protection devices.
Automated Stage Lighting Needs Isolated Data Transmission 2
Theater lighting standard DMX connects up to 512 light nodes using a serial daisy chain with EIA-485 or CAT5 for control.
More Designs Embrace The Versatile RS-422 Receiver
Answers to frequently posed questions about working with RS-422 receiver devices.
Implement Idle-Bus Failsafe In Multipoint Networks
Solving the problem of idle-bus failsafe design in RS-485 industrial networks.
Isolate Your High-Speed SPI Bus Despite Long Propagation Delays
Using an isolated serial peripheral interface (SPI) bus can be a challenge when dealing with higher speeds. Find out what the limits are.
Looking To Reduce Bus Power In Industrial Networks? Be Careful What You Wish For!
Three common termination techniques for eliminating steady-state bus-current losses in RS-485 implementations are examined and found inadvisable.
DIS Delivers A High-To-Low-Voltage Interface Solution
Digital Input Serializers, (DIS) a new class of of input devices for microcontrollers and DSPs are described.
Protect Your Network Nodes Against Transients
Review of electrostatic discharge and fast-transient immunity tests for transient voltage supression diodes used on industrial buses.
Move Over Iso Amp—Make The Switch To Digital Isolation
Isolation is a means of preventing current from flowing between two communicating points. Typically, isolation is used in two situations. The first is where there's the potential for current surges that may damage equipment or harm humans. The second
