Hongtao Zhang received his Ph.D. degree in Electrical and Computer Engineering from University of California, San Diego in 2006. He joined Xilinx in 2013 and is now a senior staff Design Engineer, working on SerDes architecture development and circuit design. From 2010 to 2013, he was with SerDes design team at Oracle Corporation, where he worked on circuit design and architecture modeling. Prior to that, he worked on SerDes characterization at Texas Instruments, Dallas. His current interests are SerDes architecture development and modeling, high speed mixed-signal circuit design and optimization, and system level modeling.
Data converter based SerDes designs are gaining popularity due to their architecture flexibility as well as the capability to implement FFE through powerful DSP. This paper provides a theoretical analysis, realistic simulations and practical comparisons between TX side FFE and RX side FFE.
