Ron,
Unfortunately, I have no idea what the crystals sub circuit is! As I said previously, I am new to XTAL oscillators. I was planning to work it all out for myself and teach myself the basics of them, but without any luck.
The crystals that I have (10 from eBay), have KDSIL down the side, and nothing else. I won them months ago on eBay, so the auction page is no longer viewable, so I can't get you any more information! All I know, well assume, is that they are 32 kHz. They are in metal cans which are about 8mm in length and 3mm in diameter.
Can I ask how you got the simulation to run, and what software you are using? Thank you for the help so far though, and sorry I can't provide you with more information.
