Hi A lot will depend on the internal construction of the SMD crystal. You would want to avoid evacuated packages. They will indeed respond much faster than a conventional leaded BAW.
You may be surprised at just how good the tempco is on your junk box crystals. For a good thermometer cut you want something above 10 ppm / C. To get that with an AT bar, you just about have to put it in the dicing saw backwards.

That reduces lag quite a bit. You can do the same by using a modern SMD X-tal... And I don't have ready access to SAW devices, whereas I have tons of Xtals of all sorts in my junkbox. -- 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] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
