The MAX3986 is a 4-channel low-power linear equalizer optimized for use up to 10.3Gbps that compensates for losses encountered with FR-4 stripline and twin-ax cable. This linear equalizer is intended for use with decision- feedback equalizers (DFEs) integrated into ASICs as well as other applications where increased margin is needed rather than full signal regeneration. DFEs can typically handle 20dB of channel loss at a frequency half the bit rate, assuming the channel is not degraded by reflections and crosstalk. The extended linear range of the MAX3986 preserves the essential signal characteristics needed for optimum DFE performance. The analog equalization of the MAX3986 adds to the effectiveness of the DFE. This increases margin to tolerate environmental and manufacturing variations or to increase the length of the transmission line. The MAX3986 operates from a single 3.3V supply and is housed in a lead-free, 5mm x 7mm TQFN package.
