Abstract
10Base-T/100Base-TX, the prevalent local area network (LAN) standard, is operated at symbol rate of 20 or 125 Mb/s through category-5 unshelled twist pair (UTP). A DSP based equalizer is presented in order to adaptively recover data sequence from received signal. The structure of decision feedback equalizer (DFE) allows error rate performance of cable length as long as 160m. Fabricated in a 0.18 μm N-well CMOS process, both digital and mixed signal simulation show error rate < 10-10.
