Dear Expert,
Hello, I am designing a high speed system.Since I don't know my
driver's output resistance, thus the termination resistor value is not
known. Thus may I use the variable resistor? If I use the variable
resistor, the size is big thus I am unable to put all the resistor near the
driver.( I have more than 10 outputs needs to be terminated). Which means
the termination resistor could not be put close to the drivers.
However, if I use a fixed and small size resistor, I need to trim
the resistor manually when I doing the testing.
So may I know that which one is more suitable? Thanks.
