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.

1. Transmit Mode

2. Receive Mode

3. 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.
