Description

The PI2EQX6874 is a 6.5Gbps low power, 4 lane (8-channel) SAS2, SATA3, XAUI signal ReDriver. The device provides programmable equalization, amplification, and de-emphasis by I²C control, to optimize performance
over a variety of physical mediums by reducing Inter-symbol interference.
PI2EQX6874 supports eight 100-Ohm Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a backplane, or 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 de-emphasis circuitry provides flexibility with signal integrity of the signal after the ReDriver. 
In addition to providing signal re-conditioning, Diodes Incorporated PI2EQX6874 also provides power management Stand-by mode operated by a Power Down pin, or through I² C register. When input is idle, the device goes into power saving Slumber mode.
