[time-nuts] Looking for TCXO data

Hello Gerald,

	You're in luck! I bought a similar one from ebay this time 
last year, and the vendor sent me a MuRata catalogue.  It is 992 KB, 
so I've put it on my website:

	http://www.barney-wol.net/private/MuRata_oscillators.pdf

Your OC2545 is on page 21 (the 23rd page of the document!). You might 
be in luck again, as it says standard frequencies were 10 and 12 MHz, 
and the "1000" is just a number assigned by the factory.  The D 
suffix means 12 volts, and the T means TTL output levels (that isn't 
mentioned on the 2545 page, so is perhaps unusual, but is defined on 
page 6 - Part Numbering)

	Happy New Year,

		Peter
