Description

A5, A6

Input

RX2_IN+, RX2_IN−

Differential Input for Main Receiver 2. When unused, connect these pins

to ground.

A9, A10

Input

RX1_IN+, RX1_IN−

Differential Input for Main Receiver 1. When unused, connect these

pins to ground.

A12, A13

Input

ORX1_IN+, ORX1_IN−

Differential Input for Observation Receiver 1. When unused, connect

these pins to ground.

Input

VDDA1P3_RX_RF

Observation Receiver Supply.

B7, B8

Input

RF_EXT_LO_I/O−,

RF_EXT_LO_I/O+,

Differential External LO Input/Output. If these pins are used for the

external LO, the input frequency must be 2× the desired carrier

frequency. When unused, do not connect these pins.

Input/

output

GPIO_3P3_0

GPIO Pin Referenced to 3.3 V Supply. The alternate function is AUXDAC_4.

Because this pin contains an input stage, the voltage on the pin must

be controlled. When unused, this pin can be tied to ground through a

resistor (to safeguard against misconfiguration), or this pin can be left

floating, programmed as outputs, and driven low.

Input/

output

GPIO_3P3_3

GPIO Pin Referenced to 3.3 V Supply. Because this pin contains an input

stage, the voltage on the pin must be controlled. When unused, this pin

can be tied to ground through a resistor (to safeguard against

misconfiguration), or these pins can be left floating, programmed as

outputs, and driven low.

C13

Input/

output

GPIO_3P3_9

GPIO Pin Referenced to 3.3 V Supply. The alternative function is

AUXDAC_9. Because this pin contains an input stage, the voltage on

the pin must be controlled. When unused, this pin can be tied to

ground through a resistor (to safeguard against misconfiguration), or

these pins can be left floating, programmed as outputs, and driven low.

Input/

output

GPIO_3P3_1

GPIO Pin Referenced to 3.3 V Supply. The alternative function is

AUXDAC_5. Because this pin contains an input stage, the voltage on

the pin must be controlled. When unused, this pin can be tied to

ground through a resistor (to safeguard against misconfiguration), or

these pins can be left floating, programmed as outputs, and driven low.

Input/

output

GPIO_3P3_4

GPIO Pin Referenced to 3.3 V Supply. The alternative function is

AUXDAC_6. Because this pin contains an input stage, the voltage on

the pin must be controlled. When unused, this pin can be tied to

ground through a resistor (to safeguard against misconfiguration), or

these pins can be left floating, programmed as outputs, and driven low.

D13

Input/

output

GPIO_3P3_8

GPIO Pin Referenced to 3.3 V Supply. The alternative function is

AUXDAC_1. Because this pin contains an input stage, the voltage on

the pin must be controlled. When unused, this pin can be tied to

ground through a resistor (to safeguard against misconfiguration), or

these pins can be left floating, programmed as outputs, and driven low.

D14

Input/

output

GPIO_3P3_10

GPIO Pin Referenced to 3.3 V Supply. The alternative function is

AUXDAC_0. Because this pin contains an input stage, the voltage on

the pin must be controlled. When unused, this pin can be tied to

ground through a resistor (to safeguard against misconfiguration), or

these pins can be left floating, programmed as outputs, and driven low.

Input/

output

GPIO_3P3_2

GPIO Pin Referenced to 3.3 V Supply. Because this pin contains an input

stage, the voltage on the pin must be controlled. When unused, this

pin can be tied to ground through a resistor (to safeguard against

misconfiguration), or these pins can be left floating, programmed as

outputs, and driven low.

Input/

output

GPIO_3P3_5

GPIO Pin Referenced to 3.3 V Supply. The alternative function is

AUXDAC_7. Because this pin contains an input stage, the voltage on

the pin must be controlled. When unused, this pin can be tied to

ground through a resistor (to safeguard against misconfiguration), or

these pins can be left floating, programmed as outputs, and driven low.

Input/

output

GPIO_3P3_6

GPIO Pin Referenced to 3.3 V Supply. The alternative function is

AUXDAC_8. Because this pin contains an input stage, the voltage on

the pin must be controlled. When unused, this pin can be tied to

ground through a resistor (to safeguard against misconfiguration), or

these pins can be left floating, programmed as outputs, and driven low.
