CC1310: CC1310 外部晶振和通信问题

Expert 2280 points
Part Number: CC1310

CC1310 两块板, 一块使用48M外部晶振, 一块使用24M晶振,   

1. 48M的板子和24M的板子不能通信, 接收不到数据

2. 48M的板子和 LAUNCHXL-CC1310 也无法通信

3. 24M的板子和 LAUNCHXL-CC1310 可以通信

    The CC1310 device supports two external and two internal clock sources. A 24-MHz external crystal is required as the frequency reference for the radio. This signal is doubled internally to create a 48-MHz clock. The 32.768-kHz crystal is optional. The low-speed crystal oscillator is designed for use with a 32.768-kHz watch-type crystal. The internal high-speed RC oscillator (48-MHz) can be used as a clock source for the CPU subsystem. The internal low-speed RC oscillator (32-kHz) can be used as a reference if the low-power crystal oscillator is not used. The 32-kHz clock source can be used as external clocking reference through GPIO。

    请您参考(datasheet的第42页Clock Systems部分)

  • 外部晶振只能使用24M的吗?
