Texas Instruments DS320PR1601 PCIe 5.0 32Gbps Linear Redriver

The Texas Instruments 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 inter-symbol interference (ISI) induced by an interconnect medium, such as PCB traces. A linear output driver follows the CTLE receiver. The linear datapaths of DS320PR1601 preserve the 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.
