Part Number:OMAP-L138
工程师你好!
参考的是omapl-138 LC DEV KIT,相教一下 RTC_VSS是否需要与GND相连,看原理图中只有如下两处出现:
谢谢!
Nancy Wang:
不需要跟板子上的地接到一起。请看datasheet的说明:
When an external crystal is used oscillator (OSC_VSS, RTC_VSS) ground must be kept separate from other grounds and connected directly to the crystal load capacitor ground. These pins are shorted to VSS on the device itself and should not be connected to VSS on the circuit board.
