what kind of series termination resistors should I be using for a 5Mhz digital (0 to 5V) signal which comes from a comparator on the other end of up to 45cm of ribbon cable and at least two connectors?
how does one even go about estimating this?
the comparator is a push-pull output, and is already source-terminated with 68 ohm resistor
so on the receiving end, on a different PCB, going into some TXB0108 level shifter ICs, what kind of series termination is normal/standard practice?
As a placeholder in my schematic i've put 68 ohm resistors on the receiving end and will go right at the inputs to the level shifter
