PI3EQX8908ZFE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX8908ZFE is an eight-channel PCI Express ReDriver manufactured by Diodes Incorporated. It supports serial link data rates of 2.5 Gbps, 5.0 Gbps, and 8.0 Gbps, compatible with PCIe Gen 1, Gen 2, and Gen 3 protocols. The device features independent channel configuration for receiver equalization, output swing, and gain via pin strapping or I2C control. It utilizes eight 100-Ohm differential CML data I/Os to extend signals across distant pathways. The component operates at a supply voltage of 3.3 V and is housed in a ZFE package.
