[R-390] INFO Cristal Y201 and Y203

Tue, 2 Sep 2003 14:13:18 -0700

(1) Y201, 17 MHz - this will be a SERIES mode crystal
(2) Y203, 200 kHz - this should be a PARALLEL mode crystal with parallel
capacitance of about 30 pF. That will put the proper frequency right in the
middle of the tuning range of the adjustment capacitor.

I think the package should be the HC-6/U package, but I haven't actually
looked to make sure. Anybody else know for sure?

The resistance at resonance will not be critical. Just ask for "as low as is
reasonable". For the 17 mHz, it will be around 400 ohms. For the 200 kHz, it
will be much higher.

These can be ordered from JAN crystals. Their inside sales person is Sue

I like them because they will make crystals one at a time.

You can order them from the web site at www.jancrystals.com.
Any questions you don't understand on their form, just don't bother to fill
them in. They will contact you if there is a problem.

Enjoy!
