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 3 defines these parameters. Figure 4 illustrates the operating conditions under which these parameters are tested and
specified. For Fo>90MHz, rise and fall time is measured 20 to 80%.
3. Symmetry is measured defined as 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.

Enable/Disable Functional Description
Under normal operation the Enable/Disable is left open or set to a logic high state. When the E/D is set to a
logic low, the oscillator stops and the output is in a high impedance state. This helps reduce power
consumption as well as facilitating board testing and troubleshooting.
Tri-state Functional Description
Under normal operation the tri-state is left open or set to a logic high state. When the tri-state is set to a
logic low, the oscillator remains active but the output buffer is in a high impedance state. This helps facilitate
board testing and troubleshooting.
