In my project I need 457 kHz (+/- 80 Hz) carrier frequency. As far as I know there is no fixed oscillator for that frequency (or any oscillator which output you can divide to get it).
I plan to use programmable crystal oscillator from Epson - series SG-8000 ( **broken link removed** ) and divide the output frequency by 4 or 8 with binary counter like 74HC393. The oscillator alone have frequency tolerance of at least 50 ppm so I need to do this in way that have small negative influence on output frequency. Power efficiency is also important.
Will it work? Are there better ways to solve it?
Thanks for every suggestion!
