USB Hub PCB Design Guide

flux

Here’s a solid match for a 2‑port USB 2.0 hub IC in QFN, suitable for self‑powered mode.
Recommended hub IC (QFN, self-powered capable)

Why this fits (from the datasheet)
  • Supports self‑ or bus‑powered operation; selectable via SELF_BUS_PWR bit, with optional dynamic power switching (LOCAL_PWR).
  • 2 downstream ports supported in the USB251xB family.
  • LED indicator pins available (e.g., SUSP_IND, HS_IND) for activity/status.
  • QFN 36‑pin (6x6 mm) package is available and preferred for this family.
  • Clocking: 24 MHz parallel‑resonant crystal (or external 24 MHz clock).
Would you like me to add USB2512B-AEZG to your project and proceed with its required support parts (24 MHz crystal, decoupling, strap options, CC Rd on upstream USB‑C, ESD, and labeled nets)?
