Hello everybody,
I write you because I would like to know what is the best technique to
terminate differential signaling today for LVDS and ECL.
I know there is a classic thechnique of put a resistor between tx lines with
the differential impedance value ( 2*intrinsic impedance ) to terminate the
differential-mode signal. I also know that the thevenin or AC termiantion
can be used to terminate the diffential-mode and common mode signal.
I read a lot of information about that but, is the single resitor technique
falling into disuse due to it is useless for common mode signal termination?
I ask this because ECL manufacturers do not say anything in their
application notes about single resistor technique.
Thank you. Beforehand.
