SI and EMI performance of signaling scheme through UTP cable

Abstract

Signal integrity (SI) and electromagnetic

interference (EMI) performances of single-ended and

differential-pair schemes through an unshielded twisted pair

(UTP) cable have been studied systematically through

experiment. The EMI performance is evaluated with

measurement of common-mode (CM) noise current on the UTP

cable. The SI performance is assessed by measurement of digital

waveforms with and without the UTP cable connected.
