Not sure how to tackle this issue. I have a 1.28 MHz digital clock signal with 0 = 0V, 1 = 1.5V. I need to buffer it and split it for distribution, some of the outputs will travel approximately 100 feet. I'm flexible with the output voltage but I was thinking 5 TTL. The high voltage requirements of 5V may slow it down.
Option 1) Find a clock buffer distributor chip that works, then use line driver chips
Option 2) Use a voltage comparator circuit to change levels (or a different technique), then buffer distribute and line drive
Option 3) ?????
