Automotive, PCIe 4.0 16Gbps four-channel linear redriver

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.
