Description
Pericom’s PI3EQX6741ST is a low power, signal SATA Gen 3i 6Gbps ReDriver™. The device provides programmable equal - ization and output emphasis, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interfer - ence. PI3EQX6741ST supports two 100Ω Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a back- plane, or to extend the signals across other distant data pathways on the user’s platform. The integrated equalization circuitry provides flexibilitywith signal integrity of the signal before the ReDriver. A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully inde - pendently. When the channels are enabled (EN=1) and operating, that channels input signal level (on xI+/-) determines whether the output is active. If the input signal level of the channel falls below the active threshold level (Vth-) then the outputs are driven to the common mode voltage. Termination Detect indication (TDet_A# or TDET_B#) provides indication when the load is connected ie HDD or Host. This can be used as control to go into power saving mode by either the host or HDD. In addition to signal conditioning, when EN = 0, the device enters a low power standby mode.

The user can enable TDet_EN (set to High) for eSATA application as it would save more power when there is no external HDD connection. But for internal SATA application, TDet_EN should be set to LOW because internal HDD is always on and termination is always there. When Redriver doesn’t detect Host or HDD termination, there will be about 12us detect pulse width with 50us detect period at the output of ReDriver. Once the termination is detected, the detect period will change to about 40ms. Anyway when the signal is detected at the input of redriver, there will not be any detect pulse at both the output side of redriver. 16-0050
