## Description
The DS160PR412 is a four-channel linear redriver with an integrated demultiplexer. It is designed to support PCIe 4.0 and other interfaces and uses continuous time linear equalizers (CTLE) to boost high-frequency signals, compensating for signal degradation over traces and cables. The device supports link training for optimal electrical performance.
