1. INTRODUCTION
Combo ExpressCard 3 ports, the next evolution of the PC Card, combines a smaller form
factor and faster performance with the PC Card reliability and ease of use. It is a single-chip
solution both for IEEE 1394a and USB2.0 compact size ExpressCard /34 module and the
interface has a potential transfer rate of up to 500 MB/sec (or 250 MB/sec in each direction)
using a single-lane (or x1) PCI Express link. Combo ExpressCard 3 ports was created to meet
the need of the ExpressCard market where notebooks, desktops, and docking stations could
add two additional two FireWire400 IEEE 1394a and one USB2.0 ports via a single slim-type
ExpressCard. Users will benefit from ExpressCard plug-n-play ease of use, which eliminates
the need to open the chassis to add new features. With this combo ExpressCard, you can
use both IEEE 1394a and USB2.0 multimedia peripheral, such as digital video (DV), hubs, data
storage devices, PC video cameras, and more.
