Exactly what type of signal is this?@nsaspook
yea, the idea is without using signal drivers. We would need pull-ups for the open drain lines but i am guessing the cable itself is a degrading factor. Thought about using coax but then 5 ft will be highly capacitive so the rise time will get affected, and plus pull up values have to be significantly smaller.
How will signal drivers work for a bi-directional signal?
That may not be a bad idea. This is some custom signal but open-drain bidirectional. We would need support for 200 Mbps, if we dont have any other solution, i will try RS485 as backup. Will keep posted.Exactly what type of signal is this?
5 feet is not a just connect two wires task if you want reliability in a digital signal transfer at that speed. There are RS485 half duplex (bi-directional) transceivers that can handle 100Mbps.
Open-drain, bidirectional, 200 Mbps at 5 feet. I wish you good luck with that.That may not be a bad idea. This is some custom signal but open-drain bidirectional. We would need support for 200 Mbps, if we dont have any other solution, i will try RS485 as backup. Will keep posted.
Sure, Ethernet works just fine too. It seems the OP wants a 200Mbps i2c type connection that's 5 feet long. That's a problem.I have no fear of running 100mhz data over long lines. (double terminated) I have used differential cables. Send the signal and not-signal and use good drivers and receivers.
I do not have a good idea how your bidirectional thing works.
Look at network cabling.
You survive by dealing with unexpected events in an honest and forthright manner. You make it up to the customer in whatever way you have to, and all will usually be well. If not, there is always Art History..... or squeeze them in... which is what happened to me ... I had to pay hell for all my ignorance when I first went freelancer ... although I prefer the term "noobieness" better
