PI3EQX8908A1ZFEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX8908A1 is an 8-channel PCI Express ReDriver designed for 2.5Gbps, 5.0Gbps, and 8.0Gbps serial links with linear equalization. It supports PCIe Gen 1/2/3 protocols using eight 100-Ohm differential CML data I/Os. The device features programmable linear equalization, output swing, and gain via pin strapping or I2C control to reduce inter-symbol interference. 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 Feature Summary

Supports PCIe Gen 1, 2, and 3 protocols with independent channel configuration for receiver equalization, output swing, and flat gain.
Provides fully linear transfer function compliance with PCISIG Link Training signals to optimize performance over various physical mediums.
Includes per-channel activity detection with selectable input termination and output termination detector on power up.
