Description
Vectron’s VCC1 Crystal Oscillator (XO) is quartz
stabilized square wave generator with a CMOS
output, operating off either a 1.8, 2.5, 3.3 or a 5.0
volt supply.
The VCC1 is 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.
