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 impedance-controlled traces. Additionally, ensure that the device is placed near the edge of the board to reduce signal reflections.
The DS34C87TMX requires a specific power sequencing order to prevent damage. Ensure that the VCC supply is powered up before the VCCIO supply, and that both supplies are powered down in the reverse order. Additionally, use a power sequencing controller or a voltage supervisor to ensure a clean power-up and power-down sequence.
The DS34C87TMX has a high thermal design power (TDP) of 1.4W. Ensure good thermal conductivity by using a heat sink or a thermal pad, and provide adequate airflow around the device. Also, consider using thermal interface materials to reduce thermal resistance.
The DS34C87TMX requires a stable clock source to operate correctly. Use a high-quality clock source, such as a crystal oscillator or a clock generator, and ensure that the clock signal is properly terminated and routed. Additionally, use the device's built-in clock synchronization features to minimize clock skew and jitter.
The DS34C87TMX has built-in ESD protection, but it's still essential to follow proper ESD handling procedures during assembly and testing. Use ESD-safe materials, such as ESD-safe workbenches and wrist straps, and ensure that the device is properly grounded during handling.
