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 a controlled impedance PCB, minimize vias and stubs, and use series termination resistors. Also, consider using a signal integrity analysis tool to simulate and optimize your design.
The maximum cable length supported by the DS90LT012AQMFE/NOPB depends on the specific application and the type of cable used. As a general guideline, the device supports cable lengths up to 10 meters at 1 Gbps and 3 meters at 3 Gbps.
To troubleshoot issues with the DS90LT012AQMFE/NOPB, use a logic analyzer or oscilloscope to capture and analyze the signal waveforms. Check for signal integrity issues, incorrect termination, or incorrect device configuration.
Yes, the DS90LT012AQMFE/NOPB can be used in a multi-lane configuration to increase the aggregate bandwidth. However, this requires careful planning and design to ensure proper signal routing and termination.
