According to High Speed Digital Design (A Handbook of Black Magic) use end-terminating resistors together onto a single capacitor. This provides a power saving end terminator with a guaranteed voltage from the cap.

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
