Maybe relevant question is not how [in]predictable is PLL's reaction on input frequency variation, but that there is one. I mean even if PLL reaction is predictable, *when* [thermal] variation and consequent reaction occurs is not, right? ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List openssl-dev@openssl.org Automated List Manager majord...@openssl.org
