EVALUATION KIT AVAILABLE MAX14954 Ruggedized Quad PCIe Redriver with Equalization and Extended Temperature Operation General Description Benefits and Features The MAX14954 is a quad equalizer/redriver designed to Fully Integrated for Ease of Use and Design improve PCI Express (PCIe) signal integrity by providing Flexibility programmable input equalization at its receiver and pro- Optimized for PCIe Gen III (8.0GT/s), Gen II grammable redrive circuitry. The output circuitry reestab- (5.0GT/s) Gen I (2.5 GT/s) Compatible lishes deemphasis lost on the board and compensates for Four Levels of Input Equalization Up to 16dB circuit-board loss. The device permits optimal placement Eight Levels of Output Deemphasis Up to 9dB of key PCIe components. The device is useful with strip- High Level of Performance to Overcome Noise in line, microstrip printed circuits, and balanced 100 cable. Lossy Channels The device is tailored for PCIe and features electrical idle Random Jitter: 0.5ps (typ) RMS and receiver detection on each channel. It is optimized for Deterministic Jitter: 10.5ps (typ) P-P PCIe Gen III (8.0GT/s) and Gen II (5.0GT/s) data rates, Equalization Permits Placement Up to 30in FR4 while still handling Gen I (2.5GT/s). Robust Solution for Harsh Environments The MAX14954 is available in a small, lead-free, 42-pin Industrial Temperature Rated: -40C to + 85C (3.5mm x 9.0mm) TQFN package for optimal layout and 5kV Human Body Model (HBM) Protection on minimal space requirements.
