摘要
提出了一种重影消除自适应均衡芯片设计,该芯片采用自适应算法、内置576抽头数字滤波器,可完成重影消除的所有功能。芯片高度集成,内嵌DSP控制器、存储器、同步检测器、D/A、A/D及用户编程。该芯片采用3.3V电源电压、0.35μmCMOS工艺生产制造,80-pin的QFP封装;在典型工作频率下最大功耗为1.3W。
A novel adaptive equalizer IC ,which reduces the effect of multi-path signal ghosts, is described in this paper. An adaptive algorithm was used to dramatically improve the received image quality. The device, whose internal 576-tap digital filter eliminates artifacts, performs all the functions required for ghost cancellation, eliminating the need for external DSP controllers, memory, sync detection, D/A converters, A/D converters and user programming. The device was encapsulated in 80-pin QFP and the active area is 280mm2 in a 0.35μm CMOS process, operating with 3.3V power supplies and dissipating 1.3W at a rate of 14.318 MHz （4Fsc）.
