Serial express Cards
DSPXP-100
PCI ExpressCard technology is emerging with faster speeds and better
efficiency than typical PC cards, connecting high-bandwidth peripherals to
notebooks and other portables. The serial ExpressCard’s credit-card form
factor provides a smaller, faster and more desktop-friendly format.
Since laptops often do not provide the number and variety of built-in serial
I/O ports available on a desktop PC, these one, two and four port cards can
support I/O expansion and connectivity to serial devices in mobile laptop
applications.
This 34mm PCI ExpressCard can be used in either 34 or 54mm slots. An
included 54mm adapter improves the fit and durability of 34mm cards in
larger 54mm slots and helps the card withstand normal or accidental stress
and dislodging from the slot.

about PCi expressCards
The PXP card series was designed with a PCI Express (PCIe) interface rather
than using USB controller interfaces. The PXP series is a great solution to
connect to existing peripherals and maintain compatibility and functionality
with current application software.
Advantages of a PCIe-based ExpressCard design are in the interface to the
laptop’s motherboard. The PCIe bus interface is the successor to the PCI
bus, which in turn was the successor to the ISA bus to which built-in ports
were originally attached. As such, the ExpressCard adapter utilises a PCIe-
based design and can still directly use I/O space addresses and interrupts,
thus more closely emulating built-in ports than can be done via USB-based
design.
Moreover, because there is no USB stack for the drivers to contend with,
throughput can be higher and latency will be lower (significantly in many
cases). Due to improved data transfer rate, the ExpressCard is more efficient
for multi-tasking operations. The PXP series supports data rates of up to
921.6 Kbps, providing steady flow of data throughput.
