Texas Instruments provides a recommended PCB layout in the DS90C031E-QML datasheet, but it's also recommended to follow the guidelines in the 'High-Speed PCB Layout Guidelines' application note (SLYT685) for optimal performance.
To ensure reliable operation in high-temperature environments, it's essential to follow proper thermal design and layout guidelines, including providing adequate heat sinking and airflow. Additionally, consider using thermal interface materials and thermal vias to reduce thermal resistance.
The recommended termination schemes for the DS90C031E-QML are AC-coupled 100-ohm differential termination for the transmitter and receiver, and a 50-ohm single-ended termination for the clock input. Refer to the datasheet for more information.
To troubleshoot issues with the DS90C031E-QML, start by verifying the power supply and clock input. Then, use an oscilloscope to check the signal integrity and verify that the transmitter and receiver are functioning correctly. If issues persist, consult the datasheet and application notes for guidance.
The DS90C031E-QML is designed to meet the radiation hardness assurance (RHA) levels required for space and high-reliability applications. Refer to the datasheet and Texas Instruments' radiation testing reports for specific details on the RHA levels.
