VC-820 CMOS Crystal Oscillator VC-820 Description Vectron’s VC-820 Crystal Oscillator (XO) is a quartz stabilized square wave generator with a CMOS output. The VC-820 uses a fundamental or a 3rd overtone crystal, oscillating in a fundamental tone, resulting in very low jitter performance, and a monolithic IC which improves reliability and reduces cost.

Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this datasheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Permanent damage is also possible if E/D is applied before VDD. Table 6.
