Datasheet
SMSC USB3320 25 Revision 1.0 (07-14-09)
DATASHEET
Note: This is the same as Table 40, Section 4.4 of the ULPI 1.1 specification.
Note: USB3320 does not support operation as an upstream hub port. See Section 6.2.4.3, "UTMI+
Level 3".
Note 5.1 The transceiver operation is not guaranteed in a combination that is not defined.
The USB3320 uses the 27% resistor ECN resistor tolerances. The resistor values are shown in
Table 4.5.
