MAX14954
EVALUATION KIT AVAILABLE
Ruggedized Quad PCIe Redriver with
Equalization and Extended Temperature Operation
General Description
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.
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).
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.
