PI3EQX64904 64 GT/s PAM4 4-Channel PCIe® 6.0 Linear ReDriver™

The Diodes PI3EQX64904 ReDriver is ideal for power-sensitive and mission-critical applications in data centers, networking, and high-performance computing

Image of Diodes Incorporated PI3EQX64904 64 GT/s PAM4 4-Channel PCIe 6.0 Linear ReDriver™The Diodes PI3EQX64904 high-performance, low-power 4-channel linear ReDriver is designed to support PCI Express® 6.0 and other high-speed serial interfaces operating up to 64 GT/s PAM4. Engineered by Diodes Incorporated, this device enhances signal integrity across long traces, cables, or connectors by providing programmable equalization, flat gain, and output swing control. Each of the four differential channels operates independently and supports transparent signal conditioning, making it ideal for complex system architectures. With support for I2C and pin-strap configuration, the PI3EQX64904 offers flexible integration into a wide range of platforms. Its adaptive power management and robust ESD protection make it suitable for power-sensitive and mission-critical applications in data centers, networking, and high-performance computing.
