PS8580V is an unidirectional, 4-channel linear redriver that supports PCIe® (PCI Express®) Gen 5, with data rates up to 32.0GT/s. PS8580V introduces an ultra-low latency path. It is ideal for automotive applications where ADAS processor utilized PCIe bus to achieve its reliable & massive data transfer tasks. PS8580V comes with very low power which contribute towards lower overall system power and less heat dissipation for the automotive applications.

PS8580V removes unwanted and potentially error-inducing signal distortion that occurs in the physical transmission interface including PCIe interconnect cables, PCB traces, and connectors. PS8580V enhances data transmission reliability and enables longer PCIe interconnect cables and/or PCB traces, enabling system scalability.  In a typical application the PS8580V is used in pairs, with one used for the downstream PCIe channels, and another one used for the upstream PCIe channels.
