8.1.3 Operating Characteristics
For the following conditions unless otherwise specified:
VDD = AVDD = DVDD = 3.0V to 3.6V at Tamb = -40 to +85°C; VSS = AVSS = DVSS;
Xtal Frequency = 6.144MHz ± 0.005% (50ppm);
0dBm corresponds to 775mVrms. General Control Register bit 14 = 0 (High Rx Gain turned off).
NOTE: All dBm limits TBD.
