XOUT
EZRadio peripheral crystal oscillator output. Connect to an external 26/30 MHz crystal or leave floating if
driving the XOUT pin with an external signal source.
EZRadio peripheral crystal oscillator input. Connect to an external 26/30 MHz crystal or to an external
14
XIN
clock source. If using an external clock source with no crystal, dc coupling with a nominal 0.8 VDC level is
recommended with a minimum ac amplitude of 700 mVpp. Refer to AN417 for more details about using
an external clock source.

GPIO2
General Purpose Digital I/O for the radio. May be configured to perform various EZRadio functions, in-
cluding Clock Output, FIFO Status, POR, Wake-up Timer, TRSW, AntDiversity control, etc.

GPIO3
General Purpose Digital I/O for the radio. May be configured to perform various EZRadio functions, in-
cluding Clock Output, FIFO Status, POR, Wake-up Timer, TRSW, AntDiversity control, etc.

RXP
Differential RF Input Pin of the LNA. See application schematic for example matching network.

RXN
Differential RF Input Pin of the LNA. See application schematic for example matching network.
Transmit Output Pin. +13 dBm for EZR32HG320FXXR55, R60, R67 and R69, +16 dBm for
20
TX_13/16/20 EZR32HG320FXXR61, and +20 dBm for EZR32HG320FXXR63 and R68 variants. The PA output is an
open-drain connection, so the L-C match must supply VDD (+3.3 VDC nominal) to this pin.
21 GND/DualTX_20 +20 dBm for EZR32HG320FXXR69 variant.
