The DS50PCI401 is a low power, 4 lane bidirectional buffer/equalizer designed specifically for PCI Express Gen1 and Gen2 applications. The device performs both receive equalization and transmit de-emphasis, allowing maximum flexibility of physical placement within a system. The receiver is capable of opening an input eye that is completely closed due to inter-symbol interference (ISI) induced by the interconnect medium.

The transmitter de-emphasis level can be set by the user depending on the distance from the DS50PCI401 to the PCI Express endpoint. The DS50PCI401 contains PCI Express specific functions such as Transmit Idle, RX Detection, and Beacon signal pass through.

The device will change the load impedance on its input pins based on the state of RXDETA/B inputs detection. An internal rate detection circuit is included to detect if an incoming data stream is at Gen2 data rates, and adjusts the de-emphasis on it's output accordingly. The signal conditioning provided by the device allows systems to upgrade from Gen1 data rates to Gen2 without reducing their physical reach. This is true for FR4 applications such as backplanes, as well as cable interconnect.
