MAX14954ETO+

Signal Buffers, Repeaters, Splitters Overview

The MAX14954 is a ruggedized quad equalizer and redriver designed to enhance PCI Express signal integrity. It supports PCIe Gen III (8.0GT/s), Gen II (5.0GT/s), and Gen I (2.5GT/s) data rates. The device operates from a single +3.0V to +3.6V supply, with typical current consumption of 260mA at +3.3V. It features four differential channels in a 42-pin TQFN package (3.5mm x 9.0mm). Input equalization provides up to 16dB compensation, while output deemphasis offers up to 9dB. The unit includes electrical idle detection and receiver detection on each channel. It functions within an extended temperature range of -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

Programmable input equalization and output deemphasis/preshoot to compensate for circuit-board loss
Integrated electrical idle detection and per-channel receiver detection capabilities
Robust design featuring ±5kV Human Body Model protection on all pins
Flow-through pinout architecture optimized for vibration and shock resistance

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm RoHS compliance status. Confirm that the component meets the required industrial temperature specifications (-40°C to +85°C) for your deployment environment. Ensure proper power sequencing is applied during integration to prevent damage. Check for any recent product change notifications regarding manufacturing relocation or material updates.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring signal restoration over long stripline or microstrip traces. It is suitable for applications needing independent control of input equalization and output deemphasis across four lanes. Consider its flow-through layout benefits if board space and routing complexity are constraints. Verify compatibility with the target PCIe generation speeds before implementation.
