Aptiv recommends a 4-layer PCB with a dedicated ground plane, and thermal vias under the device to dissipate heat. A thermal pad on the bottom of the device should be connected to a large copper area on the PCB to improve heat dissipation.
Aptiv recommends following the IEC 61967 standard for EMC, using a shielded enclosure, and implementing filtering and shielding techniques to minimize EMI. Additionally, ensure proper grounding and decoupling of the device.
The 13979448 requires a stable input voltage supply of 5V ±10% with a minimum of 100mA current capability. A low-ESR capacitor and a ferrite bead or common-mode choke are recommended to filter the input power supply.
Aptiv recommends using a logic analyzer or oscilloscope to debug issues. Common failure modes include overheating, overvoltage, and electrical overstress. Check the device's operating conditions, power supply, and PCB layout for potential issues.
The output stage requires a 50Ω termination, and signal integrity can be ensured by using a controlled impedance PCB, minimizing trace lengths, and using a common-mode filter or ferrite bead to reduce EMI.
