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.
