DS50PCI402 2.5 Gbps / 5.0 Gbps 4 Lane PCI Express Repeater with

Equalization and De-Emphasis

Check for Samples: DS50PCI402

FEATURES

DESCRIPTION

The DS50PCI402 is a low power, 4 lane bidirectional

•

Input and Output signal conditioning

increases PCIe reach in backplanes and

cables

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.

•

0.09 UI of residual deterministic jitter at 5Gbps

after 42” of FR4 (with Input EQ)

0.11 UI of residual deterministic jitter at 5Gbps

after 7m of PCIe Cable (with Input EQ)

0.09 UI of residual deterministic jitter at 5Gbps

with 28” of FR4 (with Output DE)

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.

0.13 UI of residual deterministic jitter at 5Gbps

with 7m of PCIe Cable (with Output DE)

•

Adjustable Transmit VOD 800 to 1200mVp-p

Automatic and manual Receiver Detection and

input termination control circuitry

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.

•

Automatic power management on an

individual lane basis via SMBus

•

Adjustable electrical idle detect threshold.

Data rate optimized 3-stage equalization to 27

dB gain

•

Data rate optimized 6-level 0 to 12 dB transmit

de-emphasis

Flow-thru pinout in 10mmx5.5mm 54-pin

leadless WQFN package

•

Single supply operation at 2.5V

>6kV HBM ESD rating

-10 to 85°C operating temperature range
