Texas Instruments provides a recommended PCB layout in the CC2564BRVMR datasheet, but it's also recommended to follow the guidelines in the TI's 'Antenna and PCB Design Considerations for the CC256x' application note.
Optimizing the antenna design involves considering factors such as antenna type, size, and placement. TI provides antenna design guidelines in the CC2564BRVMR datasheet and in the 'Antenna and PCB Design Considerations for the CC256x' application note.
The maximum transmit power of the CC2564BRVMR is +20 dBm, but this can be adjusted using the device's power control feature.
Coexistence with other wireless technologies can be implemented using the CC2564BRVMR's adaptive frequency hopping (AFH) feature, which helps to minimize interference. Additionally, TI provides guidelines for coexistence in the CC2564BRVMR datasheet and in the 'Coexistence of Bluetooth and Wi-Fi' application note.
The power consumption of the CC2564BRVMR varies depending on the operating mode. In transmit mode, the current consumption is typically around 100 mA, while in receive mode it's around 50 mA. In sleep mode, the current consumption is typically around 1 μA.
