General Description
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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
