yeah,, not so much sound like some adtran gear needed

I have to generate an alternate mark inversion signal on 1.544 MHz

Sure wish a 555 could do that.

Find a 555 timer ... I used many in the olden day when radioshacks
were king LOL!

I am thinking of using some shift registers instead of using the PI
output directly as the timing signal.
Use the PI to load them.
I love me some hardware design anyhow....

Other than setting the process priority, you may need a custom
kernel. See

Anyone know how to get my program to run on bare metal?
Or at the very least tell Linux that my program is the most
important thing in the world and service it above all other things.
I am trying to create a timing signal with the Pi. It is doing
it but the jitter is pretty bad.
I have researched trying to use an interrupt but there is a
pretty low limit on how many times per second you can fire a
hardware interrupt.
Too low for my application.
