Texas Instruments SN75LVPE3410 Four-Channel Linear Redriver

Texas Instruments SN75LVPE3410 Four-Channel Linear Redriver is a low-power, high-performance linear repeater or redriver designed to support PCI Express (PCIe™) Generation 1.0, 2.0, and 3.0. The SN75LVPE3410 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 Texas Instruments SN75LVPE3410 preserve the transmit preset signal characteristics. The linear redriver becomes part of the passive channel that, as a whole, gets link trained for the excellent transmit and receive equalization settings. This transparency in the link training protocol results in a tremendous electrical link and the 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) or by using pin control.
