[SI-LIST] Re: T-line resonant frequency

Raj, that depends on the termination scheme, and what sort of information=20
is being sent from the transmit end.  With proper end terminations, the=20
line appears infinitely long and the length really doesn't matter from a=20
reflection standpoint.  Series terminated lines can react badly to any odd=
=20
multiples of lambda, lambda / 2, or for clocks, lambda / 4.  It depends on=
=20
the signal pattern.

Regards,


Steve.
