Electrical Specifications
6.3.6
All signals detailed in this sub-section use an “IDE” buffer
type. For a detailed explanation of buffer types, see Table
2-4 "Buffer Type Characteristics" on page 28.
Note 1. Rise time and fall time defined in Figure 6-8 "USB Output Parameter Definition" on page 541.
Note 2. The rise and fall time values for a given differential pair are matched within 10%. Edges are monotonic.
Note 3. Actual value is adjustable. Values in this table require CADJ[4:0] = 0x10b:
Note 4. The rise and fall time values for a given differential pair are matched within 20%. Edges are monotonic.
