Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the signal traces short and away from the power planes. Additionally, using a 50-ohm transmission line and terminating the lines with a 50-ohm resistor can help minimize signal reflections.
To ensure reliable operation in high-temperature environments, it is recommended to derate the device's power consumption, use a heat sink, and ensure good airflow around the device. Additionally, the device should be operated within its specified temperature range of -55°C to 125°C.
The recommended termination schemes for the DS26LV32AW-QML are AC coupling with a 100-ohm differential termination, or DC coupling with a 50-ohm single-ended termination. The specific termination scheme used will depend on the application and signal requirements.
To troubleshoot signal integrity issues with the DS26LV32AW-QML, use an oscilloscope to measure the signal waveform and look for signs of signal degradation, such as ringing or overshoot. Check the PCB layout and signal routing to ensure that they are not contributing to the issue. Additionally, verify that the device is properly terminated and that the signal is within the specified voltage range.
The DS26LV32AW-QML is designed to meet the radiation hardness assurance (RHA) levels required for space and defense applications. The device is tested to ensure that it can withstand total ionizing dose (TID) radiation up to 100 krad, and single event effects (SEE) up to 80 MeV/mg/cm².
