Is it possible to run the RF on the CC430 range at a lower RF reference osscillator speed? I know that Smart studio limits the RF Xtal to between 26MHz and 27MHz but to achieve some legacy frequencies/modulation schemes on a new product we are considering this family of IC's for we would need to run off a 23.745MHz oscillator. As long as all of the internal registers are set up correctly is using this lower oscillator frequency likely to break anything. Also if the IC will work with this oscillator what will be the maximum frequency achievable in the 400MHz band?
