This is a little bit beyond "HOWTO" stuff. You need to find a suitable PLL chip. ICST is a major manufacturer of these. Most of them have anti-DYI pin-spacing though. Then you need to locate the Xtal on your motherboard which drives the clocks. Again, a good place to start is to look for a PLL chip from ICST. Usually there is a 14.318MHz xtal right next to that, but some botherboards use different frequencies these days and generate the 14.318MHz by PLL instead. You can then either remove the existing xtal and feed your signal to the right of the two holes (experiment or read datasheet for the on-board PLL chip) or you can try override it while it remains on the motherboard by feeding your signal into it. Overriding gives jitter and most modern motherboards don't like that. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
