Notes: 1. Measured and guaranteed only on the Atmel^® evaluation board, including microstrip filter, balun, and smart radio fre-
quency (smart RF) firmware. Conducted measured.
2. Timing is determined by external loop filter characteristics. Faster timing can be achieved by modification of the loop fil-
ter. For further information refer to the application notes.
3. The Gaussian filter control setting (GFCS) is used to compensate production tolerances by tuning the modulation devia-
tion in production to the nominal value of 400kHz.
4. Burst mode with 0.9% duty cycle
