A Product Line of Pb Diodes Incorporated Lead-free Green PI3EQX1204-C 12.5Gbps 4-Channel, SAS3, 10GbE ReDriver with Linear Equalization Features Description TM 1-to-12.5Gbps serial link with linear equalizer e PTh I3EQX1204-C is a 4-differential-channel ReDriver . The Supports SATA Gen1/Gen2/Gen3, SAS2/3, 10GbE, and XAUI device reduces Inter-symbol interference by providing program- protocol mable linear equalization in output swing and flat gain. This is 2 Supports 4 differential channels achieved by using the pin strapping option or I C Control to op- Handles up to 34dB channel loss (42 FR4 trace, 10 meters, or timize performance over a variety of physical mediums. SAS3 cable) e PTh I3EQX1204-C supports four 100 differential CML data Independent channel configuration of receiver equalization, I/Os and extends the signals across other distant data pathways output swing and flat gain on the users platform. Rate and coding agnostic e iTh ntegrated equalization circuitry provides signal integrity Transparent to link training, OOB, Idle efl xibility before the ReDriver, whereas the integrated linear am - 260mW per channel power dissipation with 700 mVpp output plifier/buffer circuitry provides signal integrity flexibility after swing the ReDriver. 2 Pin strap and I C selectable device programming 2 4-bit selectable address bit for I C Supply Voltage: 3.3V0.3V o o Industrial Temperature Range: -40 C to 85 C Block Diagram Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
