Performance Line Technology

ExpressCard technology is emerging with faster speeds and better efficiency than the typical PCMCIA and PC Cards, connecting high-bandwidth peripherals to notebooks and other portables. The ExpressCard’s credit-card like format gives way to a smaller, faster and more desktop-friendly format. Gone are the days of laptops manufactured with PC Card slots and are swapped out with smaller, slimmer and thinner ExpressCard portals. SuperLogics’s new Performance ExpressCard line supersedes older technology and are engineered for new laptop models.

SuperLogics’ ExpressCards are designed in the smallest form factor -34. ExpressCard 34 is compatible with all ExpressCard slots - 34/54. SuperLogics’ PXP ExpressCard solutions accommodate I/O expansion and connectivity to serial and parallel devices in mobile laptop applications. Available in one, two and four port serial configurations and one parallel port, the Performance series of ExpressCards offer easy-to-upgrade PC Card technologies, while integrating popular external peripheral functionality via ExpressCard module form-factor.

Differing from SuperLogics’ ExpressCard Connectivity line, the PXP series was designed with PCI Express (PCIe) power control and design core rather than using USB controller interfaces. Advantages of a PCIe-based ExpressCard design are in the core 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 design utilizes a PCIe-based design and can still directly use I/O space addresses and interrupts, thus more closely emulates built-in ports than can be done via USB-based design. Moreover, because there's no USB stack for the drivers to contend with, throughput can be higher and latency will be lower (considerably so in many cases).

Due to improved data transfer rate, the ExpressCard is considerably more efficient for multi-tasking operations. The PXP series support data rates of up to 921.6Kbps, which provides steady flow of data throughput.

SuperLogics’ PXP series is a great solution to connect with existing peripherals and maintain compatibility and functionality with their current application software. SuperLogics also sells and supports other ExpressCard connectivity products, including 1 and 2 port serial ExpressCards, hard drive eSATA 2.0 and Ethernet configurations.
