Texas Instruments recommends a PCB layout with a solid ground plane, short signal traces, and minimal vias to reduce signal reflections and noise. A 4-layer PCB with a dedicated ground plane is recommended for high-speed signals.
To ensure signal integrity, use a controlled impedance PCB, maintain a consistent signal trace width, and use terminations as recommended in the datasheet. Also, minimize the number of vias and use a signal integrity analysis tool to simulate and optimize the design.
The maximum cable length supported by the DS25MB100TSQ/NOPB depends on the signal frequency, cable type, and termination. As a general guideline, Texas Instruments recommends a maximum cable length of 10 inches (25 cm) for signals up to 100 MHz and 5 inches (13 cm) for signals up to 200 MHz.
To handle power sequencing and supply noise, use a power supply with a low noise output, and ensure that the power supply is stable before applying signals to the device. Use a power sequencing scheme that ensures the device is powered up and down in a controlled manner to prevent latch-up or damage.
The DS25MB100TSQ/NOPB has a maximum junction temperature of 150°C. To ensure reliable operation, maintain a maximum ambient temperature of 85°C, and use a heat sink or thermal pad to dissipate heat if the device is expected to operate at high temperatures or high power levels.
