Description
Vectron’s VCB1 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off a 3.3 or 5.0 volt supply. The VCB1 uses fundamental or 3rd overtone crystals, for output frequencies < 80MHz, resulting in low jitter performance, typically 0.5ps rms in the 12 kHz to 20MHz band. fo Output Buffer / Disable
Table 1. Electrical Performance, 5V option
- A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
- Figure 1 defines these parameters. Figure 2 illustrates the operating conditions under which these parameters are tested and
- Symmetry is measured defined as On Time/Period.
- Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration (not under
- Output will be enabled if enable/disable is left open.
