WRF_VDDLNA_1P2_5G
I
1.2V supply for the 11a-band internal
LNA: If the 5G band is not used, tie this
supply pin to WRF_VDDLNA_1P2_2G.

1.2V supply for the 11g-band internal
LNA
1.2V supply for the crystal oscillator
circuit
1.7V to 3.3V supply for the BCM4330
TCXO driver. To maintain a constant load
on the WRF_TCXO_IN pin (even when
power is removed from the BCM4330),
connect this supply pin to a 1.7V to 3.3V
supply that is always present. If not
used, this pin must be connected to
ground (see Section 3: “Frequency
References,” on page 32).
