You can also use the smaller and less flexible ICS502 etc. They have a handful of fixed ratios you cal select with pin-strapings. As long as your final frequency is in the 25-35 MHz range it will work OK. -- 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
