3 Description

The DS320PR1601 is a 32-channel (16-channel

in each direction) or x16 (16-lane) low-power highperformance

linear repeater or redriver designed

to support PCIe 5.0, CXL 2.0, UPI 2.0 and other

interfaces up to 32 Gbps.

The DS320PR1601 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 DS320PR1601 preserves 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 equalization.
