PI3EQX12902E is a low power, high performance 8 Gbps 2
channels PCIe 3.0/SATA3 linear ReDriver.
The device provides programmable equalization, linear
swing and flat gain to optimize performance over a variety
of physical mediums by reducing Inter-Symbol Interference.
PI3EQX12902E supports two 100 Ω 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 pathways on the
user’s platform.
The integrated equalization circuitry enhances the signal integrity
of the waveform through the ReDriver.
Each channel operates independently. The channels’ input signal
level determines whether the output is active.
The PI3EQX12902E is a flexible, multi-protocol linear ReDriver
designed to support new chipsets with dual protocol I/O pins,
which support 8 Gbps PCIe 3.0 and 6 Gbps SATA3 speeds. It
also supports connectors such as mSATA/M.2/SATAe/U.2 that
provide control signals.
The PI3EQX12902E is also an excellent choice for single lane
applications requiring low power and small package for docking
station connectivity.
