PCIe redriver with 4-channel equalization
The MAX14950CTO+ is a 4-channel PCIe Buffer/ReDriver from Analog Devices, designed to compensate for channel loss in high-speed serial links. Its 160 ps delay keeps the signal eye open across the lane without adding enough latency to trip PCIe link-training timeouts. The part integrates input equalization and output de-emphasis, which means it can pre-shape the transmit waveform and boost a degraded receive signal in one pass — a common requirement on motherboards and riser cards where the trace runs past the 10-inch mark.
Supply and power budget for a 4-lane redriver
Operating from a single 3V to 3.6V rail, the MAX14950CTO+ draws 328 mA typical. If the board sits in a non-conditioned enclosure above 50°C ambient, the redriver's internal PLL and equalizer blocks may drift off the PCIe Gen 3 eye mask.
Active production and compliance status
Analog Devices lists the MAX14950CTO+ as Active with ROHS3 compliance.
