The MAX14954 is a quad equalizer/redriver designed to improve PCI Express^® (PCIe) signal integrity by providing programmable input equalization at its receiver and programmable redrive circuitry. The output circuitry re-establishes 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 stripline, 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 -40°C to +85°C extended operating temperature range.
