CC2755R10: Using HFOSC as ADC clock source

Shuyang Zhong

Part Number: CC2755R10

Tool/software:

My customer would like to use CC2755 without 48MHz crystal, just use it as an MCU without RF. Does CC2755 support using internal HFOSC as clock source for ADC? In datasheet there is a statement:

Does this mean the 48MHz crystal is required by ADC?

Best regards,

Shuyang

Hello Shuyang,

I checked the datasheet, and I do believe what this means is that the Radio and ADC require an external 48 MHz Crystal oscillator. I am currently also double checking with our HW engineer as well here just to make sure!

Thanks,
Alex F

Hello Shuyang,

Our HW engineer found that the ADC can source the CLKSVT here:
