PI3EQX12904E is a low-power, high-performance 8 Gbps
4-channel 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 intersymbol interference. PI3EQX12904E
supports four 100 Ω differential CML data I/Os 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 PI3EQX12904E 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, that
provide control signals. The PI3EQX12904E is also an excellent
choice for dual lane applications requiring low power and
small package, for docking station connectivity.
