Communications & Enterprise: 5G/6G & Network Timing

Racing Toward Ultra-High-Speed, Low-Jitter Performance

Driven by AI advancement and the rapid expansion of HPC, data centers are moving toward 800Gbps and 1.6TbE architectures as new communication standards. In these ultra-high-speed environments, even minimal timing jitter can cause critical data errors, forcing designers to demand extremely low phase noise and uncompromising reliability from every component. At the same time, the competitive AI server market operates under tight development cycles, requiring parts that meet performance targets while enabling fast evaluation and seamless integration.
