초록
멀티채널 단일 종단(single-ended) 환경에서 채널 사이의 상호인덕턴스 및 상호캐패시턴스에 의한 원단누화 현상(FEXT)은 결정적으로 채널의 대역폭 감소를 일으킨다. 원단누화에 의해 누화-유발 지터(CIJ)와 누화-유발 글리치(CIG)가 생기며이들은 각각 타이밍 마진 감소와 전압 마진 감소를 일으킨다. 따라서 아이 오프닝 증가와 높은 데이터 전송속도를 얻기 위해서는 원단누화 현상을 보상해야 한다. 원단누화 보상은 송신단에서 타이밍 조절 또는 파형 변형을 통해 보상할 수 있다. 또한, 수신단에서 고역-필터를 사용하여 유사 원단누화 잡음을 만들어 보상하는 방법도 있다. 본 논문에서는 원단누화 보상의최근 기술 동향을 소개하며, 이들의 장점과 단점을 논의한다.
Abstract
In a multi-channel single-ended system, the far-end crosstalk (FEXT) due to mutual inductance and mutual capacitancebetween two adjacent channels critically limit the bandwidth. FEXT causes crosstalk-induced jitter (CIJ) andcrosstalk-induced glitch (CIG) which leads to timing margin and voltage margin degradations, respectively. Therefore,FEXT must be compensated in order to increase eye opening and achieve high data-rate. It can be compensated intransmitter by controlling the timing of the data or reshaping the waveform of the signal. Also, FEXT can becompensated in receiver by generating mimicked FEXT using high-pass filter. In this paper, recent techniques tocompensate FEXT are investigated, with discussions of their pros and cons.
