Quoting Dave McGuire <mcguire at neurotica.com>:
I designed 555s into a commercial product in 2002
and again in
2004. I needed a ~455KHz carrier generator for an IR data
transmitter, and a 555 was the easiest way to do it.
Would a crystal oscilator not have been beter for this ? I seem to
remember 555s as having a rep for not being perticually
accurate.....though I guess if it was good enough for your app, it's
prolly the simplest/cheapest solution.
Cheers.
Phill.
