USB 3.0
The PCZ-NVM is equipped with a front panel Type-A USB 3.0 receptacle (USB 3.1 Gen1
SuperSpeed 5Gbps). This port is derived from the CPU carrier card PCH (platform controller hub)
and passed across the inter-board mezzanine connector HSE1 to the PCZ-NVM.

The connector pr5V (V

) for powering external devices. The electronic power switch
(TPS2064) used on the PCZ-NVM limits the maximum V
BUS
output current to a safe level. The USB
power switch is rated at >1.5A current limit, which is suitable even for applications where heavy
capacitive loads are likely to be encountered, e.g. V
BUS
powered USB disk drives. The electronic
switch signals a fault condition to the CPU card PCH.
