Description

Vectron’s VCS3 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating from a 1.8, 2.5 or 3.3 volt supply. The VCS3 utilized a high performance, low frequency quartz resonator followed by a custom ASIC to synthesize the output frequency. fo Output Buffer / Disable

Table 1. Electrical Performance, 3.3V option

  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. For Fo>90MHz, rise and fall time is measured 20 to 80%.

  1. Symmetry is measured defined as On Time/Period.
  2. Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration (not under
  3. Output will be enabled if enable/disable is left open.
