VCC1
CMOS Crystal Oscillator
VCC1
Description
Vectron’s VCC1 Crystal Oscillator (XO) is a quartz stabilized square wave generator with a CMOS output. The VCC1 uses a fundamental or 3rd
overtone crystal resulting in very low jitter performance, and a monolithic IC which improves reliability and reduces cost.

The power supply should have by-pass capacitors as close to the supply and to ground as possible, for example 0.1 and 0.01uF.
Parameters are tested with the test circuit shown in Figure 1.
See Standard Frequencies and Ordering Information tables for more specific information.
Includes initial accuracy, operating temperature, supply voltage, shock and vibration (not under operation) and 10 years aging.
Duty Cycle is measured as On Time/Period, see Fig 2.
Broadband Period Jitter measured using a LeCroy Wavemaster 8600A, 90K samples, see Application Note for Typical Phase Noise and Jitter Performance.
The Output is Enabled if the Enable/Disable is left open.
