Description

Diodes’ PI3EQX25904 is a multi-data rate, four 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 intersymbol interference. PI3EQX25904 supports four 100Ω differential CML data I/Os 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.
