PCIe to PCI bridge module
The backplane features a PCIe to PCI bridge Module which translates the serial PCIe bus into the parallel PCI
bus. The PCI bus is needed for the connection to legacy PXI slots and devices. In order to support legacy PXI
slots as well as PXI Express fully Hybrid slots the PCIe-PCI Bridge Module is plugged between two device slots
at the rear side of the backplane.
The bridge Module is optimized for transfers from burst capable PCI Bus masters. The Module supports 32 bit 33
MHz operation as well as 32 bit 66 MHz operation.
PXIe clock module
The Hartmann Electronic PXI Express Clock Module generates clocks, according to the PXI Express Hardware
Specification, for the synchronization of PXI Express slot cards.
The PXI Express clocks are synchronized to an internal or external high accurate 10 MHz clock source. As soon
as an external clock source is available, the VCXO-based module, automatically synchronizes to the external
source. The switching between the clock sources is realized through automatic retrieve switchover. That allows
the PXI Express Chassis user to glitch free hot plug an external clock source to a running system.
