Signal Buffers, Repeaters, Splitters datasheet and documents for PI3EQX12908A2ZFEX

PI3EQX12908A2ZFEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX12908A2 is an eight-channel PCIe Gen 2, 10GbE, and SATA3 ReDriver featuring linear equalization. It operates on a single 3.3V supply within an industrial temperature range of -40°C to +85°C. The device supports data rates up to 12 Gb/s with CML differential I/Os in a 54-contact TQFN package (10mm x 5.5mm). Configuration is achieved via pin strapping or I2C interface, supporting both master and slave modes for external EEPROM loading.

Signal Buffers, Repeaters, Splitters Feature Summary

Supports PCIe Gen 1/2/3, 10GbE, and SATA3 protocols with fully compliant linear transfer functions for link training.
Provides independent per-channel configuration for receiver equalization, output swing, and flat gain.
Includes per-channel activity detection with selectable input termination and output termination detection on power-up.
Enables flexible programming through pin strapping, I2C master/slave control, or automatic loading from external EEPROM.
