S12G48的时钟PLL问题

[huangmingsong]

问题1：PLL的时钟偏差1.4%是否包含振荡器制造工艺、老化、温度和基频偏差，如不包含请分别提供。

问题2：能否提供超过 5us 的 PLL 抖动？

Hi,

A1: Yes it includes everything also including safety range for presented data. The range is not a public info but it is high enough to include all possible input factors.

A2: There is no theory related to this question. All possible data are presented in the data sheet. The data consist also safety ranges. Everything can be better but there is no guarantee for it as well as there is no procedure how to do it because it would work against presented data in the data sheet – which are guaranteed in entire range of temperatures, voltages and frequencies. Each engineer should work with worst case scenario to consider all possible conditions.

Best regards,

Ladislav
