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 filter.
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 deviation
in production to the nominal value of 400 kHz.
4. Burst mode with 0.9% duty cycle
