Notes:
General Comment: For more information, refer to Universal Serial Bus Specification, Revision 2.0, April 2000.
General Comment: The load is 100 ohm differential for these parameters, unless otherw ise specified.
General Comment: To comply w ith the values presented in this table, refer to your local
Marvell representative for register settings.
1.. Defined w ith 1.425 kilohm pull-up resistor to 3.6V.
2.. Defined w ith 14.25 kilohm pull-dow n resistor to ground.
3. Defined from 10% to 90% for rise time and 90% to 10% for fall time.
4. See "Data Signal Rise and Fall Time" w aveform.
5. Including frequency tolerance. Timing difference betw een the differential data signals.
6. Defined at crossover point of differential data signals.
