Figure 4. Example of a Daisy-Chain Thunderbolt Link Topology
Hybrid Peripheral Slot
The hybrid peripheral slot can accept the following peripheral modules:
•
A PXI Express peripheral with x8, x4, or x1 PCI Express link.
•
A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link.
•
A hybrid-compatible PXI Peripheral module modified by replacing the J2 connector with
an XJ4 connector installed in the upper eight rows of J2. Refer to the
PXI Express
Specification
for details. The PXI peripheral communicates through the backplane’s
32-bit PCI bus.
•
A CompactPCI 32-bit peripheral on the backplane’s 32-bit PCI bus.
The hybrid peripheral slot provides full PXI Express functionality and 32-bit PXI functionality
except for PXI Local Bus. The hybrid peripheral slot connects to only PXI Local Bus 6 right.
PXI Local Bus
The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with
adjacent peripheral slots.
The backplane routes PXI Local Bus 6 between PXI slots. The left local bus 6 from slot 2 and
right local bus 6 from slot 3 are not routed anywhere.
Local bus signals may range from high-speed TTL signals to analog signals as high as 42 V.
