Default TXCO change out

Can a 5v TXCO be used in place of a 3.3. volt unit. Yes I know it is a stupid question. Thanks

No don't do it. Most 3.3V electronics dislike 5V signalling but there are 5V tolerant chips. So you will have to give more info for a correct answer...

This is the reverse-a 3.3v crystal replacing a 5v. unit.

I would swear I read the opposite in post # 1. "Can a 5 V TXCO be used in place of a 3.3 V unit ?" -> So there is a 3.3 V unit that will be removed and a 5 V version will be installed... I do not understand this 100% as it is contradictive with my language its grammar...

Anyway, if the 5 V chip can be fed with 3.3 V things will be OK as long as the following chips accept 3.3 V signalling.

People invented schematics to avoid confusion....
