BCM43907 Preliminary Data Sheet
WLAN Current Consumption
d. REG_ON is low or the device is in hibernation, and all supplies are present.
e. REG_ON is high. APPS domain is powered down. WLAN domain is in low-power state retention mode. Top level
is powered up.
f. Inter-beacon current.
g. Beacon Interval = 102.4 ms. Beacon duration = 1 ms @ 1 Mbps. Average current over 3× DTIM intervals.
h. Beacon interval = 307.2 ms. Beacon duration = 1 ms @ 1 Mbps. Average current over 3× DTIM intervals.
i. Duty cycle is 100%. Carrier sense (CS) detect/packet receive.
j. Measured using packet engine test mode.
k. Carrier sense (CCA) when no carrier present.
l. Duty cycle is 100%.
