content: Hi,Today I came across microchip and found about this cool Chips,https://www.microchip.com/wwwproducts/en/EQCO31X20Who else makes them? is there any price and datasheet available?The Idea of sending data and power over a single cable has many use cases.

content: I have found older parts from microchip, Like EQCO30R5.D and EQCO30T5.D, they are 4$ in Digikey and have datasheets.I wonder if instead of 24V DC power delivery, I could use 240VAC mains as a power source (or rectified 300V DC), is it possible?

content: Microchip is the only source. 6Gbps devices have been available for years. It is the 12Gbps devices that are just rolling out.The bandwidth is asymmetrical, 1-12Gbps one direction, 21-42Mbps the other. Mostly useful for cameras.

content: Quote from: ali_asadzadeh on September 02, 2020, 06:18:40 amThe multiplexing is done by a coupling circuit so the answer is yes, if the coupling circuit is designed for it. Getting a cable that is rated for the voltage and is able to carry high frequencies well, at a reasonable cost, is another problem.For more modest bandwidth requirements, networking over power line products are commonly available.Quote from: bvwj on September 02, 2020, 08:03:42 pmAlso useful for displays, although it's more common to use Cat6A for runs too long to use HDMI.

content: QuoteI can work with 500Mbps to 1Gbps, is there any solution?QuoteThe data is coupled with caps into the cables, maybe there is a clever way of doing it to give it a higher voltage

content: There are already several devices which allow power and data over coax, until now the data rate is slower than 12,5 Gbps, but they are on it...For example...DS90UB954 with FPDLink and MAXIM with GMSL MAX9276B. They are mainly used in Camera/Radar/Lidar applications.BR
