Design Your Own PLC-Compatible PSU

Narrow-band low-frequency power-line communications (NB LF PLC) is a hot topic these days. Engineers creating PLC modems must consider which PLC standard (PRIME, G3, S-FSK) will be used and which hardware will get the best performance out of the design. The modem’s power supply unit (PSU) also is essential for good performance. The PSU supplies the PLC modem as well …

Networking Technologies Take Charge At Home And On The Road

It seems like we’ll be using wireless technologies everywhere. But we’ll never be completely wireless. Hard connections offer too many speed and reliability advantages to ever be displaced completely. In fact, some technologies will use the best of both worlds. This year, Greenvity Communications and Micrel both offered the best innovations in wired networking in home and automotive technologies alike. …

Combine an MCU and Analog Front End to Implement PLC Solutions

By Maury Wright, Electronic Products 5/16/2012 A plethora of embedded systems ranging from motor control to smart-energy applications need connectivity, and the ever-present power line may provide the most convenient media for such connectivity. Moreover, power-line communications (PLC) will likely prove vital to the smart home. However, power-line communications require robust digital signal processing (DSP) and an analog front end …
