Data rate optimized 3-stage equalization to 26 dB gain Data rate optimized 6-level 0 to 12 dB transmit de-emphasis Flow-thru pinout in 10mmx5.5mm 54-pin leadless WQFN package Single supply operation at 2.5V >6kV HBM ESD rating -10 to 85°C operating temperature range DESCRIPTION The DS50PCI401 is a low power, 4 lane bidirectional buffer/equalizer designed specifically for PCI Express Gen1 and Gen2 applications. The device performs both receive equalization and transmit de-emphasis, allowing maximum flexibility of physical placement within a system. The receiver is capable of opening an input eye that is completely closed due to intersymbol interference (ISI) induced by the interconn...
