.. and since the datasheet comed from a website that proudly disply 'crystalonics' I would venture a guess that it is likely to be OK.

Anyhow, I would, of course always prefer to work with a datasheet that has the same name as the unit I use --- as a amtter of fact I would refuse to buy anything if I did not have a correct datasheet available to me.

Now, here we have someone that has bought/found something without a proper datasheet and (s)he has 2 choices a) throw it away and buy a documented unit or b) use what is available and hope.
