Any inputs on how to convert a TTL signal from 1kohm
source to 50ohm load. Can I just use an input 50-ohm line driver directly?
(e.g. http://focus.ti.com/docs/prod/folders/p ... 4s140.html)
For this specific design the load can be either 1kohm or 50ohm.
Rise time is defined as 10ns (i.e. bandwidth of about 35MHz
[ BW = 0.35/t_rise]))
I appreciate your inputs.
