Type Description
I
1.2V analog power supply
I
1.4V to 1.8V VCO/LDO power supply input
I
1.7V to 3.3V supply for the BCM43362 TCXO driver. To maintain
a constant load on the TCXO_IN pin, even when power is
removed from the BCM43362, connect this supply pin to a 1.7V
to 3.3V supply that is present whenever the external TCXO is
powered up. Note that this should be a clean supply (do not use
VIO). If not used, this pin must be connected to ground.
I
1.2V XTAL oscillator power supply. This supply is required for
all clock options: crystal, dedicated TCXO, and shared TCXO
(WRF_TCXO_IN).
I
Internal power amplifier power supply (VBAT supported), high
current
I
Internal power amplifier driver power supply (VBAT supported)
I
1.2V AFE power supply
I
1.2V digital supply for the core
I
RF I/O and OTP supply (3.3V)
I
Digital I/O supply.
I
Digital I/O supply for SDIO interface signals.
I
1.2V analog supply to the internal LNA.
O VCO LDO output. Some designs may require a decoupling
capacitor (nominal 0.22 µF) for optimal WLAN performance.
Broadcom recommends that a 0201 size footprint for this capacitor
be included in all designs in case the capacitor is necessary.
