DESCRIPTION
The DS50PCI402 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 ...
