Krystaly emailed me asking for these specs:
we are able to produce this crystal, however we need to know the basic parameters:
- package?
- parallel or series resonance? If parallel, please specify loading .....xx... pF?
- adjustment at 25 deg C (... ppm) and temperature stability (... ppm) over operating temperature range.... (from ¡ deg C to ¡ deg C)
Can you try to specify?
Anyone have any idea?
Hi,
package = HC-6/U
parallel resonance 32pF
frequency 1648.550 KHz and 16501.550 KHz
both within 40Hz of desired frequency at 25 degrees C.
Temperature coefficient not specified.
(I'm winging it on the 40 Hz tolerance. You could make it tighter,
but the price would climb up higher.)
