Description
Pericom Semiconductor’s PI3EQX12902B is a low power,high
performance 12.5 Gbps 2 channels PCIe3.0/SAS3/SATA3/10GE
KR linear ReDriver™.
The device provides programmable equalization, linear swing
and flat gain to optimize performance over a variety of physi-
cal mediums by reducing Inter-Symbol Interference.
PI3EQX12902B supports two 100Ω Differential CML data
I/O’s between the Protocol ASIC to a switch fabric, over
cable, or to extend the signals across other distant data path-
ways on the user’s platform.
The integrated equalization circuitry provides flexibility with
signal integrity of the signal before and after the ReDriver.
Each channel operates fully independently. The channels’
input signal level determines whether the output is active.
The PI3EQX12902B is a flexible, multi-protocol linear
ReDriver designed to support new processor chipsets with
dual protocol I/O pins, supporting PCIe3 8Gbps/SAS3
12Gbps/SATA3 6Gbps speeds and connectors such as
mSATA/M.2/U.2/SATAe. The PI3EQX12902B is also an
excellent choice for single lane applications requiring low
power and small package such as docking station connectivity.
