A product Line of Diodes Incorporated PI3EQX6801A 6.5Gbps, 1-port, 1.5V/3.3V SATA/SAS ReDriver with Analog/Digital Configuration Features Description Two 6.5Gbps differential channels e PTh I3EQX6801A is a low power, 1.5V/3.3V, 6.5Gbps, SATA/SAS signal ReDriver. e dTh evice provides programmable equaliza - Output swing up to 1.2V pk-to-pk tion, to optimize performance over a variety of physical mediums SAS, SATA fully supported by reducing Inter-Symbol Interference. Adjustable Receiver Equalization - 0 to 16 dB PI3EQX6801A supports two 100 Differential CML data I/Os 100 Differential CML I/Os between the Protocol ASIC to a switch fabric, across a backplane, or to extend the signals across other distant data pathways on the Continuous step output swing adjustment users platform. Continuous step output pre-emphasis control e iTh ntegrated equalization circuitry provides flexibility with Input signal level detect and squelch for each channel signal integrity of the signal before the ReDriver. OOB fully supported A low-level input signal detection and output squelch function is Auto HDD Rate Detection for out swing/emphasis setting provided for each channel. Each channel operates fully indepen- dently. When the channels are enabled (x EN =0) and operating, Supply Voltage: 1.5V or 3.3V that channels input signal level (on xI+/-) determines whether the Low Power, 162mW 1.5V (600 mV Swing) output is active. If the input signal level of the channel falls below Stand-by Mode Power Down State: Current < 56 A the active threshold level (Vth-) then the outputs are driven to the Auto Slumber Mode power: 22.5mW typical common mode voltage. Industrial Temperature Range -40 to 85C Each lane can be powered-down if x EN =1, and when A EN and B EN are both high, the device enters a low power standby mode.
