DESCRIPTION
The DS50PCI402 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 interafter
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
DS50PCI402 to the PCI Express endpoint. The DS50PCI402 contains PCI Express specific functions
such as Transmit Idle, RX Detection, and Beacon
signal pass through.
The device provides automatic receive detection
circuitry which controls the input termination
impedance. By automatically reflecting the current
load impedance seen on the outputs back to the
corresponding inputs the DS50PCI402 becomes
completely transparent to both the PCIe root complex
and endpoint. 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.
