Diodes Incorporated's PI3EQX8908A2 is a PCIe, 8 differential channel 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 PI3EQX8908A2 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, software (I²C) or loaded via an external EEPROM. When operating in the EEPROM mode, the configuration information is automatically loaded on power up, which eliminates the need for an external microprocessor or software driver.
The PI3EQX8908A2 offers fully Linear Transfer function to fully comply with all PCIe 3 Link Training signals.
