3 Description

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.
