Note 7: CCK power at chip port. Duty cycle is 100%. Includes PA contribution at 3.6V
Note 8: OFDM power at chip port. Duty cycle is 100%. Includes PA contribution at 3.6V
Note 9: In WLAN power-saving mode, the following blocks are powered down: Crystal oscillator,
Note 8: OFDM power at chip port. Duty cycle is 100%. Includes PA contribution at 3.6V
Note 9: In WLAN power-saving mode, the following blocks are powered down: Crystal oscillator,
Baseband PLL, AFE, RF PLL, Radio
Note 10: OFDM power at chip port is 16 dBm, duty cycle is 100%, includes PA contribution at
3.6V
The above blocks are turned ON in the required order with sufficient time for them to settle.
This sequencing is done by the PMU controller that controls the settling
