New Product Databrief PI3EQX6801 6.5Gbps, 1-port, 1.5V/3.3V SATA/SAS ReDriver with Analog/Digital Configuration Pe r i c o m S e m i c o n d u c t o r s P I 3 E Q X 6 8 0 1 i s a l o w p o w e r, 1.5V/3.3V, 6.5Gbps, SATA/SAS signal ReDriver. The device Features provides programmable equalization, to optimize performance Two 6.5Gbps differential channels over a variety of physical mediums by reducing Inter- Symbol Interference. Output swing up to 1.2V pk-to-pk SAS, SATA fully supported PI3EQX6801 supports two 100 Differential CML data I/Os between the Protocol ASIC to a switch fabric, across a backplane, Adjustable Receiver Equalization - 0 to 16 dB or to extend the signals across other distant data pathways on 10 0 Dif ferential CML I/Os the user s platform. Continuous step output swing adjustment The integrated equalization circuitry provides flexibility with Continuous step output pre-emphasis control signal integrity of the signal before the ReDriver. Input signal level detec t and squelch for each channel A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully OOB fully supported independently. When the channels are enabled (x EN =0) Auto HDD Rate Detec tion for out swing/emphasis set ting and operating, that channels input signal level (on xI+/-) Supply Voltage: 1.5V or 3.3V determines whether the output is active. If the input signal level of the channel falls below the active threshold level (Vth-) then Low Power, 162mW 1.5V (60 0 mV Swing) the outputs are driven to the common mode voltage. Stand-by Mode Power Down State: Current < 56 A Each lane can be powered- down if x EN =1, and when HDD unplug power: 1.5mW A EN and B EN are both high, the device enters a low Auto Slumber Mode power: 22.5mW t ypical power standby mode.
