PI3EQX12908A

3.3V, 12Gbps 8 channel LINEAR SAS3, 10GbE, PCIe3, SATA3 Combo ReDriver with Pin Strap and I2C control, FlowThrough pinout

Product Description

The PI3EQX12908A is a PCIe3, 10GE-KR, SAS3, 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 PI3EQX12908A 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 PI3EQX12908A offers fully Linear Transfer function to fully comply with all PCIe 3, 10GE & SAS3 Link Training signals.
