The PCI Express standard has been introduced in 2004 with the goal to replace the PCI bus, which currently is the dominant bus for adding expansion cards to a PC. This new standard features a significantly improved performance when compared to the PCI bus. For instance a typical PCI bus has a maximum data throughput of approximately 1Gbps, whereas PCI Express has a scalable performance model with data rates starting at 2.0Gbps and ranging all the way up to 64Gbps.

An additional significant advantage of PCI Express is that unlike PCI the available bandwidth does not have to be shared with other expansion cards giving each PCI Express card the option to fully utilise the available bandwidth. Thanks to this huge performance potential, PCI Express is expected to soon become the dominant expansion bus for PCs.

With today's introduction of the DTA-2145 DekTec is getting ready for the future and affirming its ambition to remain a leading provider of PC based Digital-TV interface cards. This new adapter features one dedicated ASI/SDI output and one bi-directional ASI/SDI port. Thanks to the bi-directional port the DTA-2145 can be used either as full-duplex ASI/SDI input + output card or as two independent ASI/SDI outputs.

The DTA-2145 is shipped with both a low-profile and a standard-profile bracket. The low-profile bracket enables insertion of the card in servers with low-profile PCI Express slots.
