The CC2500 data sheet has the following text
Refer 26.1
The chip can alternatively be operated with a
reference signal from 26 to 27 MHz instead of
a crystal. This input clock can either be a fullswing
digital signal (0 V to VDD)
My question is whether I can eliminate the crystal from my design by providing an PWM signal generated from the MSP430F5324 MCU that I am using as the MCU in the circuit.
