英文摘要：

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.
