Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good high-speed design practices, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines.
To ensure signal integrity, use controlled impedance traces, minimize vias and stubs, and use termination resistors as recommended in the datasheet. Additionally, simulate your design using tools like IBIS or SPICE to verify signal integrity.
The maximum cable length supported by the DS90C385AMT/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 FPD-Link III applications.
To troubleshoot issues with the DS90C385AMT/NOPB, use a logic analyzer or oscilloscope to verify signal integrity and check for errors. Consult the datasheet and application notes for troubleshooting guidelines and common pitfalls to avoid.
While the DS90C385AMT/NOPB is optimized for FPD-Link III applications, it can be used in other high-speed digital applications with proper design and layout considerations. However, Texas Instruments may not provide full support for non-FPD-Link III applications.
