Zhejiang Saisi, a key pioneer of time-frequency and communication chip sector with independent R&D in China, will show its core voice communication and time-frequency synchronization solutions at MWC2026 (“The IQ Era”), March 2–5, Fira Gran Via Barcelona, Hall 5, Booth 5J64, featuring its indigenously developed high-end chips and solutions.
In voice communication, Saisi will feature full FXS single/dual-channel solutions and indigenously developed SLIC chips (AS1630, AS2630 series) for 10G PON/FTTR devices. As China’s first enterprise to independently develop SLIC chips, it has addressed key industry bottlenecks, offering cost-effective subscriber line interface solutions.
A key highlight is its end-to-end time-frequency synchronization solutions, including full-range crystal oscillators. Its new ultra-low jitter differential oscillator (25MHz~625MHz, 44fs @156.25MHz) delivers exceptional precision for high-performance AI devices and 5G-A/6G base stations, alongside atomic clocks, timing modules and clock systems for critical scenarios.
With self-developed core algorithms (FPGA timing, TDC, Kalman filtering) and integrated customization capabilities, Saisi’s products are sold in 30+ countries, solidifying its position as a key player in China’s time-frequency sector. Its participation at MWC2026 marks an important step in global expansion.
Saisi invites global partners to Hall 5, Booth 5J64 to experience its products and explore collaboration for AI-driven connectivity.
