Crystal ESR - was Cricket musings
GM John,toggle quoted messageShow quoted text
Thanks for the excellent post, good info, nothing better than having data. Cricket users have discovered that some (most) HC49S crystals wont oscillate, but that the HC49U crystals will perform ok. Actually some of those didn't oscillate reliably either, resulting in changes in R9 and R10 before going into production. In an earlier post, NM0S also provided insight into higher ESR requiring more feedback. Thanks for mentioning 200p and 470p for C9 and C10. The Cricket is a very open design and several builders have experimented with the feedback, and probably will continue to do so.
