Design of a Novel Video-Rate Adaptive Equalizer IC

Abstract
A novel video-rate adaptive equalizer IC that reduces the effect of multi-path signal echoes (ghosts),is described.An adaptive algorithm is used to dramatically improve the quality of the received image.The device,whose internal 576-tap digital filter eliminates artifacts that result from multi-path echoes,performs all the functions required for ghost cancellation and comprises DSP controllers,memory,syn detection,D/A converters,A/D converters,and user programming.The device is encapsulated in an 80-pin QFP,and the active area (PADs including) is 14mm×20mm in a 0.35μm CMOS process. It operates with a 3.3V power supply and dissipates 1.3W at the rate of 14.318MHz.-
