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 50-ohm impedance-controlled trace for the LVDS signals.
To ensure reliable operation in high-temperature environments, it's recommended to follow proper thermal design guidelines, such as providing adequate heat sinking and airflow. Additionally, the device should be operated within its specified temperature range of -40°C to 85°C.
The recommended power sequencing for the DS90LV049QMTX/NOPB is to power up the VCC supply before the VCCIO supply. This ensures that the internal voltage regulators are properly initialized.
To troubleshoot issues with the DS90LV049QMTX/NOPB, it's recommended to use a combination of oscilloscope measurements, signal integrity analysis tools, and device-specific debugging tools. Additionally, consulting the device datasheet and application notes can provide valuable insights into device operation and potential issues.
To protect the DS90LV049QMTX/NOPB from electrostatic discharge (ESD), it's recommended to follow proper handling and storage procedures, such as using ESD-safe packaging and handling the device by the body rather than the leads. Additionally, incorporating ESD protection devices, such as TVS diodes, into the PCB design can provide additional protection.
