Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as using a solid ground plane, minimizing signal trace lengths, and avoiding vias under the device. Additionally, ensure that the PCB material has a low dielectric constant to minimize signal reflections.
The SCAN92LV090VEH/NOPB has a thermal pad on the bottom, which should be connected to a solid ground plane or a thermal relief pattern on the PCB. Ensure good airflow around the device, and consider using a heat sink or thermal interface material if the device will be operating in high-temperature environments.
The maximum clock frequency for the SCAN92LV090VEH/NOPB is 100 MHz, but it's essential to consider the system's signal integrity, PCB layout, and device loading when operating at high frequencies. Ensure that the clock signal is clean and has a low jitter to prevent data corruption.
To ensure data integrity, use a robust clocking scheme, implement data buffering, and consider using error detection and correction mechanisms such as CRC or ECC. Additionally, ensure that the device is properly powered, and the power supply is clean and stable.
The SCAN92LV090VEH/NOPB requires a specific power sequencing to prevent damage or malfunction. Ensure that the VCC supply is powered up before the VREF supply, and that the VCC supply is stable before applying clock signals or input data.
