A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the center of the board, and the input and output traces should be kept short and matched to minimize reflections.
Use controlled impedance traces, minimize trace lengths, and use termination resistors to match the impedance of the transmission lines. Also, use a common mode filter or a ferrite bead to reduce electromagnetic interference (EMI).
The maximum operating temperature range for the DS50PCI402SQE/NOPB is -40°C to 85°C. However, the device can be operated at temperatures above 85°C with reduced performance and reliability.
The power sequencing requirements for the DS50PCI402SQE/NOPB are critical. The VCCO pin should be powered up first, followed by the VCCI pin. The VCCO pin should be powered down last, followed by the VCCI pin.
A 0.1 μF ceramic capacitor should be placed as close as possible to the VCCO and VCCI pins. Additional decoupling capacitors can be added in parallel to reduce the impedance of the power supply.
