PI3EQX8908AZFE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX8908AZFE is an 8-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, complying with PCIe Gen 1, Gen 2, and Gen 3 protocols. The device features eight 100-Ohm differential CML data I/Os and provides programmable linear equalization, output swing, and gain to reduce inter-symbol interference. Configuration is managed via pin strapping, I2C control, or external EEPROM loading. It operates on a single 3.3V ±0.3V supply voltage within an industrial temperature range of -40°C to +85°C. The component is housed in a 54-contact TQFN package measuring 10mm x 5.5mm x 0.5mm.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target system's power supply requirements and thermal management constraints for the industrial temperature range. Confirm that the I2C address bits are correctly configured for the intended bus topology.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing high-speed PCIe pathways requiring signal integrity restoration over lossy traces or connectors. The choice depends on the need for 8-channel parallel processing and flexible configuration methods including EEPROM automation. Consider the TQFN-54 footprint availability and the requirement for 3.3V operation in dense server environments.
