Description
Vectron’s VCC1 Crystal Oscillator (XO) is quartz
stabilized square wave generator with a CMOS
output, operating off a 1.8, 2.5, 3.3, or 5.0 volt
supply.
fo The VCC1 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 7 defines these parameters. Figure 8 illustrates the operating conditions under which parameters are tested/specified.
3. Overtone designs, output frequencies>35MHz.
4. Symmetry is measured defined as On Time/Period.
5. Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration (not under
operation).
6. Output will be enabled if enable/disable is left open.
