12Gb/s Over Four Balanced Lines Utilizing NRZ Braid Clock Signaling with 100% Data Payload and Spread Transition Scheme for 8K UHD Intra-Panel Interfaces

📋 论文概要

本文提出了一种NRZ编织时钟信号（NRZ Braid Clock Signaling）与扩展跳变方案（Spread Transition Scheme），在四根平衡线上实现12Gb/s的数据传输，无需任何编码开销，达到100%数据有效载荷。该方案解决了传统时钟恢复方案因开销导致带宽降低的问题，同时降低了EMI和时钟数据通道间的偏移。

💡 主要创新点

• 提出NRZ Braid Clock Signaling，将时钟嵌入数据流中，无需额外时钟通道或编码开销，实现100%数据有效载荷。
• 采用Spread Transition Scheme，通过扩展跳变分布减少EMI发射和时钟数据偏移，提升信号完整性。

29.5.1 is generally adopted in an intra-panel interface due to the poor signal integrity of the multi-drop topology, data and clock channel skews and EMI emission from the forwarded clock signal channels. Clock recovery in RX without a reference clock channel is usually carried out using one of two type of data encoding schemes, embedded clock with dummy clock bits [1-2,5] or ensured transition density with data encoding such as 8B10B encoding [3]. However, these two schemes reduce the effective bandwidth because they require over 20% overhead in the data stream. Although highly efficient signaling schemes have been introduced recently in the literature [4] to cope with the physical limitations of the process and channel, it is difficult to adopt these multi-level signaling schemes in intra-panel
