MAX14950
Quad PCI Express Equalizer/Redriver
General Description
Features
S Optimized for Generation III (8.0GT/s) and
The MAX14950 is a quad equalizer/redriver designed to
improve PCI Express® (PCIe) signal integrity by provid-
ing programmable input equalization at its receiver and
programmable redrive circuitry. The output circuitry re-
establishes deemphasis lost on the board and compen-
sates for circuit-board loss. The device permits optimal
placement of key PCIe components. The device is useful
with stripline, microstrip printed circuits, and balanced
100I cable.
Generation II (5.0GT/s) with Generation I (2.5GT/s)
Compatibility
S Receive Detection Permits Completely
Transparent, Software-Free Operation
S Equalization Permits Placement of Up to 30in FR4
S PCIe Gen III (8.0GT/s)-Compliant Input/Output
Return Loss
S Electrical Idle Detection
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).
