Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the signal traces as short as possible. Additionally, it's recommended to use a common mode filter and to decouple the power supply with capacitors.
To ensure reliable operation in high-temperature environments, it's recommended to follow the thermal design guidelines provided by Texas Instruments, including using a heat sink and ensuring good airflow around the device. Additionally, the device should be operated within its specified temperature range.
The recommended termination scheme for the DS92LX1622SQE/NOPB is to use a 100-ohm differential termination resistor at the receiver end, and to use a 50-ohm single-ended termination resistor at the transmitter end.
To troubleshoot issues with the DS92LX1622SQE/NOPB, it's recommended to use oscilloscopes and logic analyzers to capture and analyze the signal waveforms. Additionally, checking the power supply voltage, signal termination, and PCB layout can help identify the root cause of the issue.
Yes, when designing with the DS92LX1622SQE/NOPB, it's recommended to follow good EMI/EMC design practices, such as using shielding, filtering, and grounding techniques to minimize electromagnetic interference. Additionally, the device should be placed in a shielded enclosure to reduce radiated emissions.
