AD6190
Mode Controls
The AD6190 is designed as a time-division-duplex (TDD)
radio. This means that the transmitter and receiver operate at
different times. The AD6190 includes control pins to shut down
unused portions of the circuit when not needed, saving power,
as shown in the table below. For any mode except “Sleep,”
power must be applied to VBATT Pin 3 and to all VCC Pins
(16, 21 and 26) to ensure proper operation.
NOTE: Do not enable both the transmit and receive paths
simultaneously.
