Texas Instruments provides a recommended PCB layout in the CC8521RHAR datasheet (section 10.1) and in the CC8521RHAR Evaluation Module User's Guide (section 4.1). It's essential to follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
To minimize power consumption, configure the CC8521RHAR in low-power mode (LPM) by setting the LPM pin high. Additionally, adjust the transmit power level, data rate, and packet size according to your application's requirements. Refer to the datasheet (section 7.3) for more information on power management.
The CC8521RHAR is rated for operation from -40°C to 85°C (industrial temperature range). However, it's essential to ensure proper thermal management and heat dissipation to prevent overheating, especially in high-power transmission modes.
Yes, the CC8521RHAR can be used with an external antenna. However, it's crucial to ensure the antenna is designed for the 2.4-GHz frequency band and has a suitable impedance match to prevent signal degradation and ensure optimal performance.
The CC8521RHAR supports frequency hopping, which can be implemented using the device's built-in frequency synthesizer and the TI 15.4-Stack software. Refer to the CC8521RHAR datasheet (section 7.4) and the 15.4-Stack user's guide for more information on frequency hopping implementation.
