2019年3月7日 · In this paper, a 3b/2UI PAM-3 singleended memory interface is proposed, with a pin efficiency of 150% and a reduced clock frequency, compared to NRZ signaling. To address PAM-3 equalizer inefficiencies a tri-level decision feedback equalizer (DFE) …

However, the increased data rate incurs higher inter-symbol interference (ISI), while PAM3 is more vulnerable to ISI than PAM2 signaling. Decision feedback equalizers (DFEs) are widely used in receivers (RX) to remove post-cursor ISI without amplifying noise.

PAM-3 has been identified as a suitable modulation scheme for 1000 base-T1. Line coding or mapping between bits and symbols needs to be defined. Tradeoff between BW efficiency and other desired properties. Small run length of consecutive symbols of the same value. ISI/error propagation control. Finite running digital sum: unnecessary.

2023年9月22日 · Three-level Pulse Amplitude Modulation (PAM3) is a high-speed modulation technique that converts the binary bit stream into three-level symbols so as to reduce the bandwidth requirement on the frequency spectrum, at the cost of a lowered eye height (EH) and associated complexity.

In this paper, a 3b/2UI PAM-3 single-ended memory interface is proposed, with a pin efficiency of 150% and a reduced clock frequency, compared to NRZ signaling. To address PAM-3 equalizer inefficiencies a tri-level decision feedback equalizer (DFE) is implemented in the receiver (RX).
