Description
Vectron’s VCC4 Crystal Oscillator (XO) is quartz
stabilized square wave generator with a CMOS
output, operating off either 1.8, 2.5, 3.3 or 5.0 volt
supply.
The VCC4 uses fundamental or 3
rd
overtone
crystals for output frequencies >50MHz resulting
in low jitter performance. Also a monolithic IC,
which improves reliability and reduces cost, is
hermitically sealed.
