CC1100E SWRS082 Page 53 of 92 If OOK modulation is used, the logic 0 and logic 1 power levels shall be programmed to index 0 and 1 respectively. Table 33 contains recommended PATABLE settings for various output levels and frequency bands. DN013 Error! Reference source not found. gives the complete tables for the different frequency bands. Using PA settings from 0x61 to 0x6F is not recommended. Table 34 contains output power and current consumption for default PATABLE setting (0xC6). programming details. must be programmed in burst mode if you want to write to other entries than PATABLE[0]. Table 34: Optimum PATABLE Settings for Various Output Power Levels and Frequency Bands Table 35: Output Power and Current Consumption for Default PATABLE Setting 25 Shaping and PA Ramping With ASK modulation, up to eight power settings are used for shaping. The modulator contains a counter that counts up when transmitting a one and down when transmitting a zero. The counter counts at a rate equal to 8 times the symbol rate. The counter saturates and 0 respectively. This counter value is used as an index for a lookup in the power table. Thus, in order to utilize the whole table, FREND0.PA_POWER should be 7 when ASK is active. The shaping of the ASK signal is dependent on the 480 MHz 955 MHz Output Power [dBm] Setting Current Consumption, Typ. [mA] Setting Current Consumption, Typ.
