VC-820中文资料CMOS Clock Oscillator数据手册Microchip规格书

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.

简介

VC-820属于晶体振荡器谐振器的振荡器。由制造生产的VC-820振荡器振荡器产品用作频率/时间基准源，与常用于类似用途的晶体产品相比，区别在于它们集成了更多功能，用于生成输出的保持和稳定。最简单的振荡器包括晶体或其他谐振元件，并且具备必要的功能，让用户能够获取频率基准，而无需密切关注谐振元件的工作。更先进的器件还集成了温度补偿或控制功能，以获取更稳定的基准或能够进行选择性调节的基准。
