PI2EQX6812

Product Description

The PI2EQX6812 is a low power, SAS2, 2-lane (4 differential channels) SATA, XAUI signal ReDriver. The device provides programmable equalization, amplification, and de-emphasis by either pin strapping option or I²C Control, to optimize performance over a variety of physical mediums by reducing Inter-symbol interference.

PI2EQX6812 supports four 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, the PI2EQX6812 also provides power management Stand-by mode operated by a Power Down pin, or through I²C register. When the input is idle, the device goes to power saving slumber mode
