PI2EQX6812  
6.5Gbps 2-Lane (4-channel)SAS2/SATA/XAUI ReDriver™ with Equalization & De-emphasis  
Features  
Description  
ÎUp to 6.5Gbps SAS2/SATA/XAUI ReDriver™  
ÎSupporting 4 differential channels or 2 lane  
ÎIndependent channel configuration  
Pericom Semiconductor’s PI2EQX6812 is a low power, SAS2,  
2-lane (4 differential channels) SATA, XAUI signal ReDriver™.  
e device provides programmable equalization, amplification,  
2
and de-emphasis by either pin strapping option or I C Control,  
2
ÎPin strap and I C configuration controls (3.3V Tolerant)  
to optimize performance over a variety of physical mediums by  
reducing Inter-symbol interference.  
ÎAdjustable receiver equalization  
ÎAdjustable transmitter amplitude and de-emphasis  
ÎAdjustable input threshold level  
Î50-Ohm input/output termination  
ÎMux/Demux and loop-back features  
ÎOOB fully supported  
ÎSingle supply voltage, 1.2V 5%  
ÎActive current per channel -95mA (typical)  
ÎPower down standby mode  
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.  
e 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 aꢀer the ReDriver.  
In addition to providing signal re-conditioning, Pericom’s  
PI2EQX6812 also provides power management Stand-by mode  
à Standby current -1mA (typical)  
ÎAutomatic slumber mode power savings  
2
operated by a Power Down pin, or through I C register. When  
à Slumber current per channel -10mA (typical)  
the input is idle, the device goes to power saving slumber mode

ÎIndustrial operating temperature range: -40 C to 85 C  
ÎPackaging (Pb-free & Green):  
à 42-contact TQFN (9mm x3.5mm)
