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.
