PI3EQX10904 (Obsolete)

3.3V, 10Gbps 4 channel LINEAR 10GbE ReDriver with Pin Strap and I2C control, FlowThrough pinout


The PI3EQX10904 is a 10Gigabit Ethernet, 4 differential channels ReDriver. The device provides programmable linear equalization, output swing and flat gain, by either pin strapping option or I²C Control, to optimize performance over a variety of physical mediums by reducing Inter-symbol interference. PI3EQX10904 supports four 100-Ohm Differential CML data I/O’s and extends the signals across other distant data pathways on the user’s platform. The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver, whereas the integrated circuitry provides flexibility with signal integrity of the signal after the ReDriver.
