VC-820数据手册晶体振荡器谐振器的振荡器规格书PDF

描述 Description

The VC-820 Crystal Oscillator (XO) is a quartz stabilized square wave generator with a CMOS output. The VC-820 uses 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.
