The MAX14950A is a single-lane PCIe equalizer/redriver from Maxim that provides programmable input equalization for improving PCI Express® (PCIe) signal integrity. It features innovative design, single +3.3V supply operation, increased design flexibility, optimized for PCIe Gen III (8GT/s) and Gen II (5GT/s) signals, high level of integration and very low latency.
The MAX14950A dual equalizer/redriver improves PCIe signal integrity by providing programmable input equalization and output emphasis. It supports PCIe Gen III (8 GT/s), Gen II (5 GT/s) and Gen I (2.5 GT/s) with very low latency (≈160 ps) and includes electrical idle detection.
The device is offered in a 40‑pin 5.0 mm × 5.0 mm TQFN package with an exposed pad for efficient thermal dissipation. Recommended layout practices include separate layers for receive and transmit signals and close placement of decoupling capacitors. Proper power‑supply sequencing (GND then VCC) is required for reliable operation.
