Notes:
1. The frequency range is continuous over the specified range.
2. The frequency step size is limited by the frequency noise.
3. Optimum differential load is equal to 3.5 V/(11.5 mA/2 x 4/PI) = 480 Therefore the antenna load resistance
4. Total NVM copy time = 2 ms + (NVM copy Boot Time per kB) x (NVM data in kB).

in parallel with the Si4010 differential output resistance should equal 480
