一文了解均衡的秘密之FFE

说完CTLE之后,大家不用猜都知道会讲FFE。的确,FFE(Feed Forward Equalization前向反馈均衡)和前面CTLE有一些相似之处,它们都是模拟的均衡器,同时也是线性的。当然说模拟,线性什么的比较抽象,实际上我认为它们还有更大的相似之处,先卖个关子,下面会描述到。 还是按照 ...

均衡的秘密！FFE与CTLE有何相似之处？

FFE和之前讲过的CTLE有一些相似之处，它们都是模拟的均衡器，同时也是线性的。模拟、线性这样的描述都很抽象，本文将介绍它们之间更大的相似之处。 说完CTLE之后，大家不用猜都知道会讲FFE。的确，FFE（Feed Forward Equalization前向反馈均衡）和前面CTLE有一些 ...

How much attenuation is too much?: Rule of Thumb #10

This rule of thumb enables us to estimate how much attenuation would be in the loss budget of a serial channel. Spoiler summary:With no equalization, about -10 dB at the Nyquist. With just CTLE, about ...

Analyzing post-equalization ISI with pulse response

Analyzing closed eye diagrams is tricky. The primary eye-closing culprit is inter-symbol interference ISI), which is caused by the frequency response of the channel. I’ve written about closed eye ...
