PRELIMINARY INFORMATION - COMPANY CONFIDENTIAL A product Line of Diodes Incorporated PI3EQX12902A 12Gbps 1 Port/2 Channels SAS3/10GE/PCIe3/SATA3 Combo ReDriver with Linear Equalization Features Description 12Gbps serial link with linear equalizer. PI3EQX12902A is a low power, high performance 12Gbps 2 Two 12Gbps differential signal pairs channels SAS3/10GE/PCIe3/SATA3 linear ReDriver. Support SAS3/10GE/PCIe3/SATA3 protocols e dTh evice provides programmable equalization, linear Transparent to link training, OOB, Idle swing and flat gain to optimize performance over a variety Pin Adjustable Receiver Equalization of physical mediums by reducing Inter-Symbol Interference. Pin Adjustable output linear swing PI3EQX12902A supports two 100 Differential CML data I/Os Pin Adjustable Flat Gain between the Protocol ASIC to a switch fabric, over cable, or to ex- 100 Differential CML I/Os tend the signals across other distant data pathways on the users platform. Auto receiver detection for adaptive power management Autolow powe mode for adaptive power management e iTh ntegrated equalization circuitry provides flexibility with Single Supply Voltage: 3.3V 0.3V signal integrity of the signal before and after the ReDriver. o o Industrial Temperature range: -40 C to 85 C Each channel operates fully independently. The channels input Packaging: (Pb-free & Green) signal level determines whether the output is active. 30-pin, TQFN 2.5x4.5 mm (ZL30) e Th PI3EQX12902A is a efl xible, multi-protocol linear ReDriver designed to support new processor chipsets with dual protocol Applications I/O pins, supporting SAS3 12Gbps, 10GE 10Gbps, PCIe3 8Gbps, SATA3 6Gbps speeds and connectors such as mSATA/M.2/ Notebook PC SATAe/U.2 that can provide control signals. Server motherboards Rack server e PTh I3EQX12902A is also an excellent choice for single lane ap - JBOD storage plications requiring low power and small package such as docking Blade server station connectivity.
