MAX14954

Ruggedized Quad PCIe Redriver with

Equalization and Extended Temperature Operation

General Description

Beneﬁts and Features

● Fully Integrated for Ease of Use and Design

The MAX14954 is a quad equalizer/redriver designed to

improve PCI Express® (PCIe) signal integrity by providing

programmable input equalization at its receiver and pro-

grammable redrive circuitry. The output circuitry reestab-

lishes deemphasis lost on the board and compensates for

circuit-board loss. The device permits optimal placement

of key PCIe components. The device is useful with strip-

line, microstrip printed circuits, and balanced 100Ω cable.

Flexibility

• Optimized for PCIe Gen III (8.0GT/s), Gen II

(5.0GT/s); Gen I (2.5 GT/s) Compatible

• Four Levels of Input Equalization Up to 16dB

• Eight Levels of Output Deemphasis Up to 9dB

● High Level of Performance to Overcome Noise in

Lossy Channels

The device is tailored for PCIe and features electrical idle

and receiver detection on each channel. It is optimized for

PCIe Gen III (8.0GT/s) and Gen II (5.0GT/s) data rates,

while still handling Gen I (2.5GT/s).

• Random Jitter: 0.5ps

• Deterministic Jitter: 10.5ps

• Equalization Permits Placement Up to 30in FR4

● Robust Solution for Harsh Environments

• Industrial Temperature Rated: -40°C to + 85°C

• ±5kV Human Body Model (HBM) Protection on

All Pins

The MAX14954 is available in a small, lead-free, 42-pin

(3.5mm x 9.0mm) TQFN package for optimal layout and

minimal space requirements. The device is specified over

-40NC to +85NC extended operating temperature range.

• Housed in a Flow-Through (3.5mm x 9.5mm)

TQFN Package for Resistance to Vibration/

Shocks

Applications

● Industrial/Embedded PCs

● Computer on Modules

● Carrier Boards
