VXA5 Microprocessor Crystals
The VXA5 series of HC-49/U packaged crystals offers the most
popular crystal package for computer and peripherals'
applications. Our type "A" package (HC-49/U) offers the highest
level of quality at the most economical price.
Vite's standard crystal tolerance (Option "B" under stability vs.
temperature) is 50 PPM -20C to +70C relative to the load
capacitance at +25C. All VXA crystals will operate -40C to +85
C. The "B" stability of 50 PPM is an absolute guarantee but the
typical crystal is better than 30 PPM 0C to +70C and better than 75 PPM from -40C to
+85C.
