- Silicon Revision 2.0 (vs AM5728BABCXEA)
Design Notes
The AM5728BABCXA requires multiple power rails (VDD_MPU, VDD_DSP, VDD_CORE, VDD_IO) with specific sequencing. Use a PMIC like TPS6594-Q1 to manage power-up and power-down sequences. Ensure adequate decoupling capacitors (100nF and 10uF) near each power pin to minimize noise and voltage droop during high-current transients.
The AM5728BABCXA can dissipate significant power, especially when both ARM and DSP cores are active. Use a heatsink or thermal pad on the FCBGA package and ensure proper airflow in the enclosure. The thermal resistance (theta_JA) is [DATA_NEEDED] °C/W; calculate junction temperature to ensure it stays below the maximum rating. Consider using a thermal simulation tool to optimize PCB copper pour for heat spreading.
For high-speed interfaces like DDR3, USB 3.0, and PCIe, follow the layout guidelines in the AM5728 datasheet. Maintain controlled impedance for differential pairs (e.g., 100 ohms for USB/PCIe) and keep trace lengths matched. Place termination resistors close to the receiver. Use a solid ground plane and minimize vias to reduce signal integrity issues.
