B
backplane an assembly, typically a printed circuit board (PCB), with 96-pin
connectors and signal paths that bus the connector pins. PXI systems
have two connectors, called the J1 and J2 connectors.
bus the group of conductors that interconnect individual circuitry in a
computer. Typically, a bus is the expansion vehicle to which I/O or
other devices are connected. An example of a PC bus is the PCI bus.

CLKIN CLKIN is a signal connected to the SMB input pin of the same name.
CLKIN also can serve as PXI_CLK10_IN.
CLKOUT CLKOUT is the signal on the SMB output pin of the same name.
PXI_CLK10 can be routed to CLKOUT.
clock hardware component that controls timing for reading from or writing
to groups
CompactPCI an adaptation of the Peripheral Component Interconnect (PCI)
Specification 2.1 or later for industrial and/or embedded applications
requiring a more robust mechanical form factor than desktop PCI. It
uses industry standard mechanical components and high-performance
connector technologies to provide an optimized system intended for
rugged applications. It is electrically compatible with the PCI
Specification, which enables low-cost PCI components to be utilized
in a mechanical form factor suited for rugged environments.
