VXA4 Microprocessor Crystals
The VXA4 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 -20°C to +70°C relative to the load
capacitance at +25°C. All VXA crystals will operate -40°C to +85° C.
The "B" stability of ±50 PPM is an absolute guarantee but the
typical crystal is better than ±30 PPM 0°C to +70°C and better than
±75 PPM from -40°C to +85°C.
