Diodes Incorporated has expanded its ReDriver family with its first device to reach PCI Express (PCIe) 6.0 protocol speeds (up to 64 GT/s) while backward compatible with PCIe 5.0/4.0/3.0 protocols. The low-power PI3EQX64904 linear ReDriver targets a range of computing and networking applications. These include AI data centers (storage and servers), workstations, 5G networking, CPU-to-network (PCIe NIC card) and CPU-to-storage (NVME) interconnects; and CPU-to-CPU interconnects within high-performance computing clusters.

The four-differential-channel PI3EQX64904 ReDriver provides linear equalization with tunable low-frequency and high-frequency zeros at the equalizer stage to boost the PAM4 signal quality of high-speed PCIe interfaces, Diodes said, delivering reliable PCIe communications at 64 GT/s PAM4 with low bit error rates (BER).

Diodes said performance is optimized over a variety of physical media by reducing intersymbol interference, correcting for known channel losses at the transmitter, and restoring signal integrity at the receiver to meet the margins needed for PCIe communications at 64 GT/s.

The PI3EQX64904 meets Microsoft’s Modern Standby mode requirements, consuming less than 5 mW of power when the system is in PCIe L.1.2 deep standby mode. The device also delivers elevated linearity, ultra-low jitter characteristics, and low latency.

The PI3EQX64904 ReDriver, requiring a supply voltage of 3.3 V ±0.3 V, can operate over an industrial temperature range of -40°C to 85°C. The device is available in a 31-contact W-LGA-31L (6.1mm x 2.7mm) package

The PI3EQX64904 ReDriver is priced at $5.00 each in quantities of 3,000. Diodes will showcase the new ReDriver at the PCI-SIG Developers Conference, Santa Clara, CA, June 11-12, at booth #11.
