3 Description

The DS160PR410 is a four channel low-power highperformance

linear repeater/redriver designed to

support PCI Express (PCIe) Generation 1.0, 2.0, 3.0

and 4.0. The device is a protocol agnostic linear

redriver that can operate for interfaces up to 25 Gbps

including Ultra Path Interface (UPI) 2.0.

The DS160PR410 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 intersymbol

interference (ISI) induced by an interconnect

medium, such as PCB traces. The CTLE receiver is

followed by a linear output driver. The linear

datapaths of DS160PR410 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

result in best electrical link and lowest possible

latency. The programmable equalization of the device

along with its linear datapaths maximizes the

flexibility of physical placement within the

interconnect channel and improves overall channel

performance.

The programmable settings can be applied easily

through software (SMBus or I2C), direct loading from

an external EEPROM, or by using pin control. In

EEPROM mode, the configurations are automatically

loaded on power up, eliminating the need for an

external microprocessor or software driver.
