摘要

介绍了一种由256/64 QAM解调器、VSB解调器、FEC解码器和QPSK解调器组成的单片机。为了减小面积，我们针对VSB/QAM解调器采用了完整的均衡器共享架构，针对FEC解码器完成了MPEG帧格式化的全字节操作，实现了30%的压缩。

An area-effective 1-chip VSB/QAM LSI for US digital TV broadcasting

A single chip consisting of a 256/64 QAM demodulator, a VSB demodulator, a FEC decoder, and a QPSK demodulator is described. To reduce area, we adopted a complete shared architecture of the equalizer regarding the VSB/QAM demodulator, and accomplished the entire byte operation of MPEG frame formatting regarding the FEC decoder, which realized thirty percent reduction.
