Additional Details

The MC13173FTB typically operates from a 2.1 V to 3.6 V supply voltage. It features a programmable output power level, allowing the user to optimize the communication range and power consumption. The device also includes a sleep mode to further reduce power consumption when not actively transmitting data. The modulation type (FSK, ASK, or OOK) and data rate can be configured through a serial interface.
