1.3 USB Compliant
The FT4232H is fully compliant with the USB 2.0 specification and has been given the USB-IF Test-ID (TID)
40720024.
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.
