Active State Operational Modes#

The SiWx917 can be in any of the three operational modes in its Active state. Each operational mode consumes a different amount of current.

• Transmit Mode

• Receive Mode

• Listen Mode

Transmit Mode#

In the Transmit Mode, all the power domains of the SiWx917 are powered-on, except the receiver sections of the Base Band Processor (BBP), Analog Front End (AFE), and RF Front End (RFFE) domains. This is the highest power-consuming mode.

Receive Mode#

In the Receive Mode, the transmit sections of the BBP, AFE, and RFFE are powered-off.

Listen Mode#

This mode is a subset of the receive mode. In Listen Mode, the transmit sections of BBP, AFE, and RFFE are powered-off. Certain receive portions of the BBP and AFE are powered-off as no packet reception is in progress.
