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. Additionally, it's recommended to place the device near the connector and to use a common mode filter to reduce EMI.
To ensure signal integrity, it's recommended to use a transmission line with a controlled impedance, such as a 50-ohm or 75-ohm trace. Additionally, use a common mode filter to reduce EMI, and consider using a signal conditioning circuit to improve signal quality. It's also important to follow proper termination techniques and to use a low-jitter clock source.
The maximum cable length supported by the DS92LV2411SQ/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 data rates up to 1.5 Gbps. For longer cable lengths, it's recommended to use a repeater or an active cable extender.
To troubleshoot issues with the DS92LV2411SQ/NOPB, start by checking the power supply and clock signals to ensure they are within the recommended specifications. Use an oscilloscope to check the signal quality and look for signs of signal degradation, such as jitter or ringing. Check the PCB layout and ensure that it follows the recommended guidelines. Also, check the device's configuration and settings to ensure they are correct. If the issue persists, consider using a signal analyzer or a protocol analyzer to debug the issue.
The DS92LV2411SQ/NOPB is designed specifically for LVDS applications, and it's not recommended to use it with single-ended signals. However, if you need to interface with a single-ended signal, you can use an LVDS-to-single-ended converter or a signal conditioning circuit to convert the signal. Keep in mind that this may affect the signal quality and integrity.
