PI3EQX32908EZRIEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX32908EZRIEX is an eight-channel linear ReDriver designed for high-speed serial links up to 32 Gbps. It supports PCIe 5.0, SAS4/UPI, and CXL protocols. The device operates on a single 3.3V ±0.3V supply voltage within an industrial temperature range of –40°C to +85°C. It features independent channel configuration for receiver equalization, output swing, and flat gain via I2C control or pin strapping. The component utilizes a 62-contact W-QFN3590-62 package and includes I2C master mode capability for external EEPROM support.
