Title
(EN) EQUALIZER AND TRANSMITTER INCLUDING THE SAME
(ZH) 均衡器和包括均衡器的发送器
Abstract
(EN) The invention provides an equalizer and a transmitter including the same. An integrated circuit for generating an equalized signal, according to a channel, from serial data includes a shift register that extracts a symbol sequence from the serial data. A data storage stores values of an equalized digital signal corresponding to potential symbol sequences corresponding to a filter coefficient sequence. A lookup table outputs the equalized digital signal of a value corresponding to the extracted symbol sequence. A digital-to-analog converter (DAC) converts the equalized digital signal into the equalized signal. A controller refreshes the lookup table, based on at least one of values stored in the data storage and values included in the lookup table, in response to a control signal.
(ZH) 公开了一种均衡器和包括均衡器的发送器。一种用于根据信道从串行数据生成均衡信号的集成电路包括:移位寄存器,从串行数据提取符号序列。数据存储器存储与对应于滤波器系数序列的潜在符号序列对应的均衡数字信号的值。查找表输出与提取的符号序列对应的值均衡数字信号。数模转换器(DAC)将均衡数字信号转换为均衡信号。控制器响应于控制信号基于存储在数据存储器中的值和包括在查找表中的值中的至少一个来刷新查找表。
