The PI3EQX1204-C is a SAS3, 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. PI3EQX1204-C 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 linear amplifier/buffer circuitry provides flexibility with signal integrity of the signal after the ReDriver.
