TTL impedance converter - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

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.
