Core Viewpoint - The article discusses the importance of PCIe Retimer technology in enhancing signal integrity and extending transmission distances in high-speed data applications, particularly in data centers and computing systems. Group 1: PCIe Technology Overview - PCIe technology has evolved significantly, with transmission rates increasing from 2.5 GTps in PCIe 1.0 to 64.0 GTps in PCIe 6.0, and PCIe 7.0 expected to reach 128 GT/s by 2025 [7][10]. - The continuous upgrades in PCIe standards have made it a critical component in modern computing platforms [7]. Group 2: Retimer vs Redriver - Retimer technology is a mixed-signal device that can recover and regenerate data signals, improving signal quality compared to Redriver, which simply amplifies signals [12][16]. - Retimer actively participates in the PCIe protocol, while Redriver does not, leading to differences in their capabilities regarding jitter reduction and signal integrity [22][23]. - Retimer can reset the entire jitter budget and provide diagnostic capabilities, whereas Redriver lacks these features and may amplify noise along with the signal [23][27]. Group 3: Market Insights - The PCIe Retimer market is primarily dominated by companies like Astera Labs, which was the first to mass-produce PCIe 5.0 Retimer chips, and 澜起科技, which has launched PCIe 6.0 Retimer chips [36][37]. - The pricing for PCIe 5.0 Retimer chips is estimated at approximately $36 for X8 and $54 for X16 channels, with market potential calculated based on various server configurations [34][32]. - The ratio of GPUs to Retimers in high-performance servers varies, with examples including a 1:1 ratio in DGX A100 servers and a 1:3 ratio in AWS trn2 servers [32][33].
