PI3EQX8908A1 (Obsolete)

Description

The PI3EQX8908A1 is a PCIe, 8 differential channels  ReDriver™. The device provides programmable linear equalization, output swing and gain, by either pin strapping option or I²C Control, to optimize performance over a variety of physical mediums by reducing Inter-symbol interference.

The PI3EQX8908A1 supports eight 100-Ohm Differential CML data I/O’s and extends the signals across other distant data pathways on the user’s platform.

The programmable settings can be applied easily via pins or software (I²C).

The PI3EQX8908A1 offers fully Linear Transfer function to fully comply with all PCIe 3 Link Training signals.
