Diodes Incorporated


The PI3EQX32908 is a multi-data rate, 8-differential channel ReDriver™. The device provides programmable linear equalization, output swing and flat gain, through I2C control interface, and is optimized for performance over a variety of physical media with reduced Inter-Symbol Interference.

The PI3EQX32908 supports eight 100Ω differential CML data I/O’s and extends signals across data pathways on the user’s platform.

The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver, while the integrated linear amplifier/buffer circuitry provides flexibility with signal integrity of the signal after the ReDriver.
