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.
