I am inclined to agree with this, but there seems to be no
"right" termination. You could use in line termination
as well. I recommend that you use whatever the manufacturer
recommends as this is the condition that they tested the
component under. It supposedly should give you the best
results. But you must examine your situation carefully
to be sure that all conditions of the circuit are met.
Hope this is of some help,

Hello Gurus,
I would like to know the information about the standard differential
pair termination used in present high speed design world
I had gone through some of the article/doc from standard vendor like TI,
Onsemi . But every vendor defining their own termination scheme for diff
pair for PECL, GTL, BTL interfaces.
Is there any standard termination available for diff pair?
Could anyone pls provide the standard diff pair for PECL, LVPECL, GTL,
BTL … interfaces?
Thanks&Regards
Gopalakrishnan
