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 differential signal pair with a controlled impedance of 100 ohms, and maintain a consistent signal trace length and width. Also, use a common mode filter or a common mode choke to reduce electromagnetic interference (EMI).
The maximum cable length supported by the DS99R105SQX/NOPB depends on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths up to 10 meters at a data rate of 10.3125 Gbps.
To troubleshoot issues with the DS99R105SQX/NOPB, use a logic analyzer or an oscilloscope to monitor the signal quality and integrity. Check for signal attenuation, jitter, and skew, and verify that the device is properly configured and powered.
Yes, the DS99R105SQX/NOPB is compatible with other Texas Instruments devices, such as the DP83822 and the DP83825. However, it's recommended to verify compatibility and interoperability before designing a system.
