GPIO_0 to GPIO_18

I/O

General-Purpose Digital Inputs and Outputs.

See Figure 2 to match the ball location to the

GPIO_x signal name. If unused, these pins can

be connected to VSSA with a 10 kΩ resistor or

configured as outputs, driven low, and left

disconnected.

E11

TX2_EN

Enable Input for Transmitter Channel 2.

Connect to VSSA if unused.

E13, E14

ORX1+, ORX1−

Differential Input for Observation Receiver

Channel 1. Connect to VSSA if unused.

E16, F16

EXT_LO1+,

EXT_LO1−

I/O

Differential External LO Input/Output 1. If used

for the external LO input, the input frequency

must be 2× the desired carrier frequency. Do

not connect if unused. External LO functionality

not currently supported.

E17

AUXADC_1

Auxiliary ADC 1 Input. Do not connect if

unused.

AUXADC_2

Auxiliary ADC 2 Input. Do not connect if

unused.

F7, F11, L7, L11

ORX_CTRL_C,

ORX_CTRL_B,

ORX_CTRL_D,

ORX_CTRL_A

Determine Active Observation Receiver Path.

Connect to VSSA directly or with a pull-down

resistor if unused.
