Broadcom recommends a 4-layer PCB with a solid ground plane, and thermal vias under the package to dissipate heat. A thermal pad on the bottom of the package should be connected to a heat sink or a thermal interface material.
Use a differential pair routing for high-speed signals, keep signal traces short and away from noise sources, and use a common mode filter or a pi-filter to reduce EMI emissions.
Power up the device in the following sequence: VCC, then AVCC, then DVCC. The reset timing is typically 10ms, but can be adjusted based on system requirements.
Use the device's register programming interface to configure the data rate, protocol, and other settings. Refer to the datasheet and programming guide for specific register settings and values.
Perform functional testing, signal integrity testing, and environmental testing (temperature, humidity, vibration) to validate the device's performance and reliability.
