a. VDD_RF collectively refers to the VDDPX and VDDRF RF power supplies.
b. If VDDO is not applied, voltage should never be applied to any digital I/O pins (I/O pins should never be driven
or pulled high). The list of digital I/O pins includes the following (these pins are listed in Section 7: “Pin and
Signal Descriptions,” on page 40 with VDDO shown as their power domain):
GPIO[3], GPIO[5], GPIO[6]
SCL, SDA
N_MODE
SPIM_CS_N, SPIM_CLK

a. VDD_RF collectively refers to the VDDPX and VDDRF RF power supplies.
b. Overall performance defined using integrated regulation.
c. VDDTF for Class 2 must be connected to VREG (main LDO output). VDDTF for Class 1 must be connected to
VREGHV (HV LDO output) or an external voltage source. Refer to the Broadcom compatibility guide for
configuration details. VDDTF requires a capacitor to ground. The value of the capacitor must be tuned to
ensure optimal RF RX sensitivity. The typical capacitor value is 10 pF for both packages. The value may
depend on board layout.
