PI3EQX12902EZLEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX12902EZLEX is an 8 Gbps, two-channel PCIe 3.0/SATA3 combo ReDriver manufactured by Diodes Incorporated. It operates on a single 3.3 V ± 0.3 V supply and supports industrial temperatures from -40°C to +85°C. The device features pin-adjustable receiver equalization, linear swing, and flat gain to mitigate inter-symbol interference. It utilizes 100 Ω differential CML I/Os and includes auto receiver detection for adaptive power management, supporting L1.2 mode. Packaged in a 30-contact TQFN (ZL) with a Tape/Reel suffix, it is fully RoHS compliant and halogen-free.
