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.
The VCC1 uses fundamental or 3
rd
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.
