USB Digital Isolation HUB High-Speed

• SKU：EP-0243U

Descriptions

This 4-port USB 2.0 High-Speed Isolated HUB is designed to provide reliable and safe USB connectivity with electrical isolation. It utilizes the ADuM3165 chip to ensure high-level isolation protection with a 3.75 kV RMS isolation voltage. The HUB supports all USB 2.0 signaling modes, including high-speed (480 Mbps), full-speed (12 Mbps) data rates. It enables bidirectional data transfer between upstream and downstream ports while effectively removing input jitter through redriving and high-speed data retiming. This HUB is ideal for industrial, medical, and other environments where USB peripheral connectivity and electrical isolation are essential for safety and reliability.
