Description

Vectron’s VCA3 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off a 3.3 or 5.0 volt supply. The VCA3 uses fundamental or 3rd overtone crystals , for output frequencies < 80MHz, resulting in low jitter performance, typically 0.5p s rms in the 12 kHz to 20MHz band. fo Output Buffer / Disable

  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
  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
  5. Output will be enabled if enable/disable is left open.
