Texas Instruments recommends a 4-layer PCB with a solid ground plane and a separate power plane for the device. The device should be placed near the center of the board, and the input and output traces should be routed away from each other to minimize crosstalk.
To ensure signal integrity, use controlled impedance traces, minimize trace lengths, and use termination resistors at the receiver end. Also, use a common mode filter or a ferrite bead to reduce electromagnetic interference (EMI).
The maximum cable length supported by the DS90CF386MTD/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 3.125 Gbps.
To troubleshoot issues with the DS90CF386MTD/NOPB, use an oscilloscope to check the signal quality and amplitude at the input and output of the device. Also, check the power supply voltage and the termination resistors to ensure they are within the recommended specifications.
The DS90CF386MTD/NOPB is rated for operation up to 85°C. However, the device's performance may degrade at higher temperatures. If you need to operate the device in a high-temperature environment, consider using a heat sink or a thermal management system to keep the device within its recommended operating temperature range.
