PI2EQX8804ANJE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX8804ANJE is an 8.0Gbps 4-lane PCIe® 3.0 ReDriver™ manufactured by Diodes Incorporated (formerly Pericom). It operates on a single 1.5V supply and features 8 differential channels supporting x4 lane applications for PCIe 1.0, 2.0, and 3.0. The device provides programmable equalization, pre-emphasis, and output voltage swing control to reduce inter-symbol interference. It includes selectable input termination between 50Ω to VDD and Hi-Z, and selectable output termination between 50Ω to VDD and 2KΩ to VDD. Configuration is managed via I2C/SMBus or pin straps with 3-bit address selection.
