Description
Vectron’s VCC1 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off either a 1.8, 2.5, 3.3 or a 5.0 volt supply.
f
o
The VCC1 is uses fundamental or 3rd overtone crystals resulting in low jitter performance, typically 0.5pS rms in the 12 kHz to 20MHz band. Also a monolithic IC, which improves reliability and reduces cost, is hermitically sealed.

1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
2. Figure 1 defines these parameters. Figure 2 illustrates the operating conditions under which these parameters are tested and specified.
3. Symmetry is measured defined as Vs, On Time/Period.
4. Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration (not under operation).
5. Output will be enabled if enable/disable is left open.
