Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-speed PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using impedance-controlled traces.
To ensure signal integrity, use a signal integrity analysis tool to simulate the signal transmission and reception. Also, follow best practices for signal routing, such as using differential pairs, and consider using signal conditioning components like terminators or filters if necessary.
The maximum cable length supported by the DS100BR111ASQE/NOPB depends on the specific application and the type of cable used. As a general guideline, the datasheet recommends a maximum cable length of 10 meters for Category 5e or higher cables. However, it's recommended to consult with a signal integrity expert or perform simulations to determine the maximum cable length for a specific application.
To troubleshoot issues with the DS100BR111ASQE/NOPB, start by checking the power supply and clock signals. Use an oscilloscope to verify the signal integrity and check for any signal reflections or distortions. Also, consult the datasheet and application notes for troubleshooting guidelines and common pitfalls to avoid.
While the DS100BR111ASQE/NOPB is designed for PCIe applications, it can be used in other high-speed applications with proper signal conditioning and termination. However, it's essential to consult with a signal integrity expert and perform simulations to ensure the device can meet the specific application requirements.
