A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a common mode filter and a shielded cable for the USB interface.
Use a metal shield around the device, and ensure that the PCB layout is designed to minimize radiation. Use a common mode filter and a shielded cable for the USB interface. Follow the guidelines in the IEC 61000-4-x standards for EMC testing.
The maximum cable length supported by the IP4220CZ6 is 3 meters for a standard USB cable. However, this can be extended up to 5 meters using an active repeater or a USB hub.
The IP4220CZ6 has a built-in power management system that can be controlled through the I2C interface. Use the PMU (Power Management Unit) registers to configure the power modes and voltage regulators.
The IP4220CZ6 has a maximum junction temperature of 150°C. Ensure good airflow around the device, and use a heat sink if necessary. Follow the thermal design guidelines in the datasheet to prevent overheating.
