Dear sir,
I am interesting about high speed multiplexers. Now I have a question about Rds_on.
When turn on the FET, there are Rds_on and parasitic capacitance on the signal trace. It will be a RC delay circuit.
There are a description from E2E --> We use a rough formula “Bandwidth = (3/2)xDataRate” which will provide sufficient margin. Does it have a limitation about PCB trace?
I have another question. There are three different Ron characteristics – Ron, Ron(p), ∆Ron. How this three characteristics affect our design?
Regards,
Ben
