1.3 USB Compliant
The FT2232H is fully compliant with the USB 2.0 specification and has been given the USB-IF Test-ID
(TID) 40720019.
The timing of the rise/fall time of the USB signals is not only dependant on the USB signal drivers, it is
also dependant system and is affected by factors such as PCB layout, external components and any
transient protection present on the USB signals. For USB compliance these may require a slight
adjustment. This timing can be modified through a programmable setting stored in the same external
EEPROM that is used for the USB descriptors. Timing can also be changed by adding appropriate passive
components to the USB signals.
