USB 2.0 is supported in the MMI block in Versal AI Edge Series Gen 2. MMI USB 2.0 PCB guidelines for impedance, trace length, spacing, and skew are shown in the following table.
| DP0/DN0 Pair | Specification |
|---|---|
| Impedance | 90 (diff) ±10% |
| Trace length | < 10 inches |
| Skew matching between P/N pair | ±1 ps (P/M) |
| Spacing to other USB2 pairs | < 0.5 mm |
| Spacing to non-USV2 signals | 5X trace width |
USB 2.0 termination specifications are as follows:
- USB2_VBUS0: 200 Ω to ground
- USB2_TXRTUNE: 10 kΩ to ground
