DS160PR1601 PCIe® 16Gbps Linear Redriver

Texas Instruments DS160PR1601 PCIe® 16Gbps Linear Redriver is a 32-channel (16-channel in each direction) x16 (16-lane) low-power high-performance linear repeater or redriver designed to support PCIe 4.0, UPI 2.0, and other interfaces up to 16Gbps. The DS160PR1601 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 datapaths of Texas Instruments DS160PR1601 preserves transmit preset signal characteristics. The linear redriver becomes part of the passive channel that, as a whole, gets link trained for best transmit and receive equalization settings. This transparency in the link training protocol results in the best electrical link and lowest possible latency. Low channel-channel cross-talk, low additive jitter, and excellent return loss make the device almost a passive element in the link, but with its equalization.
