Diodes Incorporated PI3EQX25904 25Gbps Rate 4-Channel ReDriver

Diodes Incorporated PI3EQX25904 25Gbps Rate 4-Channel ReDriver provides programmable linear equalization, output swing, and flat gain. This integration is accomplished by either a pin strapping option or I2C control to optimize performance over various physical mediums by reducing intersymbol interference. The Diodes Incorporated 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 the signal integrity of the signal before the ReDriver. In comparison, the integrated linear amplifier/buffer circuitry provides flexibility with signal integrity of the signal after the ReDriver.
