Omap-l138上电疑问

Other Parts Discussed in Thread: OMAP-L138

现OMAP-L138要运行在456MHz,有如下几个疑问: 1. CVDD,RVDD上电是否直接加1.3V,还是先加1.2V,再调整到1.3V; 2. Datasheet中给出RTC_CVDD, PLL0_VDDA, PLL1_VDDA, SATA_CVDD, USB_CVDD的NOM电压为1.2V,MAX电压为1.32V,为符合datasheet中的上电顺序,给其提供和CVDD一样的1.3V,那是否可保证稳定运行,如果不能加1.3V,那要运行在456MHz,上电顺序是怎样的。
