This is also a frequency divider. You could probably run this directly from the osc out pin. You'd have to bring the voltage down, of course. -- Friendly Regards Tjaart van der Walt mailto:tjaart@wasp.co.za _____________________________________________________________ | Another sun-deprived R&D Engineer slaving away in a dungeon | | WASP International http://wasp.co.za | | GSM and GPS value-added applications | | Voice : +27-(0)11-622-8686 | Fax : +27-(0)11-622-8686 | |_____________________________________________________________|
