Texas Instruments provides a recommended PCB layout in the CC2564BYFVR datasheet, but it's also recommended to follow the guidelines in the TI's 'Antenna and PCB Design Considerations for the CC2564' application note (SWRA419).
Optimizing the antenna design involves considering factors such as antenna type, size, and placement. TI provides antenna design guidelines in the CC2564BYFVR datasheet and in the 'Antenna and PCB Design Considerations for the CC2564' application note (SWRA419).
The maximum transmit power of the CC2564BYFVR is +20 dBm (100 mW) for Bluetooth BR/EDR and +10 dBm (10 mW) for Bluetooth Low Energy (BLE).
TI provides guidelines for coexistence in the CC2564BYFVR datasheet and in the 'Coexistence of CC2564 with Other Wireless Technologies' application note (SWRA420).
The power consumption of the CC2564BYFVR varies depending on the mode: Rx mode: 90 mA, Tx mode: 115 mA, Idle mode: 50 mA, and Sleep mode: 10 μA (typical values).
