Redrivers and retimers are also known as "signal conditioners", because it's what they do - to improve the quality of a marginal or non-compliant signal. They are used in many different interfaces to accommodate long cable/board run - USB, HDMI, DisplayPort, SATA, just to name a few [0]. USB is a relatively new market since USB 3.1 and USB 3.2, due to its signal integrity challenge at high data rate. Retimers are digital repeaters. Redrivers are mostly analog, but they are not unity-gain amplifiers, often they do equalization and emphasis internally to compensate for the distortion at high frequency.
