PI3EQX6741ST
3.3V, 1-port, SATA3 ReDriver™ with Adjustable Equalization/Pre-Emphasis
New Product Databrief
Pericom’s PI3EQX6741ST is a low power, signal SATA3 6Gbps
ReDriver™. The device provides programmable equalization
and output emphasis, to optimize performance over a variety
of physical mediums by reducing Inter-Symbol Interference.
PI3EQX6741ST supports two 100Ω Differential CML data
I/O’s between the Protocol ASIC to a switch fabric, across a
backplane, or to extend the signals across other distant data
pathways on the user’s platform.
The integrated equalization circuitry provides flexibility with
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
independently. 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.
