Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good high-speed design practices, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines.
To ensure signal integrity, use a controlled impedance PCB design, minimize signal reflections, and use termination resistors as recommended in the datasheet. Additionally, consider using simulation tools to analyze signal integrity before prototyping.
The maximum cable length supported by the DS90UR905QSQ/NOPB depends on the specific application and the type of cable used. As a general guideline, the datasheet recommends a maximum cable length of 10 meters for FPD-Link III applications.
The DS90UR905QSQ/NOPB can be configured using the SPI interface. Refer to the datasheet for the register map and configuration details. You can also use the TI's FPD-Link III configuration tool to simplify the configuration process.
The power sequencing requirements for the DS90UR905QSQ/NOPB are critical to ensure proper operation. The datasheet recommends a specific power-up sequence, and it's essential to follow this sequence to avoid damage to the device.
