It is       unlikely the original part was specified to 1 ppm, 100 ppm would likely       do the job just fine. Didn't you say this was for a display? It will       probably work fine with just five digits or even four digits of       frequency specified. Is either 8.867 MHz or 8.868 MHz a common value       perhaps? Really anything near 8.87 MHz should do the job.              --              Rick              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
