Title: Does exist alternative for YAMAR PLC chips for DC lines?
Post by: Miyuki on April 20, 2021, 07:58:40 am
Hi.
Just wonder. Is there any alternative for YAMARs chips when I want UART or CAN ower DC line? It looks to me like the only manufacturer of this solution. Is it really so low demand market?  :wtf:

a bit late reply, but have a look to

- Texas Instruments THVD8000 RS-485 Transceiver with OOK Modulation for Power Line Communication up to 1mbps
- M-Bus interface chips like XI'AN Supermicro SE722, gatemode MC8721C, Holtek HT45B0003 / HT45B0005
- EDN article "Simple Circuit Communicates Over Low-Voltage Power Lines" by Julia Truchsess
- article "Circuit Implementation of OOK Modulation for Low-Speed Power Line Communication Using X10 Standard" by Chia-Hung WANG, Chia-Yu CHEN, and Tai-Ping SUN

I have not checked the status of these chips, but at least the THVD8000 is brand new.

Thanks, that THVD8000 looks like a nice solution, integrated without plenty of external components and for a reasonable price.
And have documentation and is available  :-+
