3. The MediaLB driver can release the MLBDAT/MLBSIG line as soon as MLBCLK is low; however, the logic state of the final
driven bit on the line must remain on the bus for tmdzh. Therefore, coupling must be minimized while meeting the
maximum load capacitance listed.
USB electrical specifications
4.4.6.1 USB electrical specifications
The USB electricals for the USB On-the-Go module conform to the standards
documented by the Universal Serial Bus Implementers Forum. For the most up-to-date
standards, visit http://www.usb.org.
4.4.6.2 ULPI timing specifications
The ULPI interface is fully compliant with the industry standard UTMI+ Low Pin
Interface. Control and data timing requirements for the ULPI pins are given in the
following table. These timings apply to synchronous mode only. All timings are
measured with respect to the clock as seen at the USB_CLKIN pin.
