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 thermal plane on the PCB.
Use a differential pair routing for the high-speed signals, keep the signal traces short and away from noise sources, and use a common mode filter or a pi-filter to reduce EMI.
Power up the device in the following sequence: VCC, then AVCC, and finally DVCC. Ensure that the power supplies are stable and within the recommended voltage range before applying the clock signal.
Use a logic analyzer or an oscilloscope to capture the signal waveforms, and verify that the clock signal is stable and within the recommended frequency range. Check the power supply voltages and ensure that they are within the recommended range.
The recommended clock signal frequency is 100 MHz, and the jitter tolerance is 100 ps. Ensure that the clock signal meets these requirements to ensure reliable data transmission.
