DS160PR410RGFRQ1-Texas Instruments-Price, Stock & Datasheet

The DS160PR410-Q1 is a four channel low-power high-performance linear redriver with integrated two 2x2 cross-point mux designed to support PCIe® 4.0 and other interfaces up to 20Gbps.

The DS160PR410-Q1 receivers deploy continuous time linear equalizers (CTLE) to provide a programmable high-frequency boost. The equalizer can open an input eye that is completely closed due to inter-symbol interference (ISI) induced by an interconnect medium, such as PCB traces. The CTLE receiver is followed by a linear output driver. The linear data-paths of DS160PR410-Q1 preserve transmit preset signal characteristics. The linear redriver becomes part of the passive channel that as a whole get link trained for best transmit and receive equalization settings. This transparency in the link training protocol results in best electrical link and lowest possible latency. Low channel-channel cross-talk, low additive jitter and excellent return loss makes the device almost a passive element in the link, but with its useful equalization. The data-path of the device uses an internally regulated power rail that provides high immunity to any supply noise on the board. The device also has low AC and DC gain variation providing consistent equalization in high volume platform deployment.
