JIAXING, China, Feb. 25, 2026 — Zhejiang Saisi, a prominent pioneer in the time-frequency and communication chip sector with independent R&D capabilities in China, is set to showcase its core voice communication and time-frequency synchronization solutions at MWC2026 (“The IQ Era”). Taking place March 2–5 at Fira Gran Via Barcelona, Hall 5, Booth 5J64, the event will feature the company’s indigenously developed high-end chips and solutions.
In the realm of voice communication, Saisi will present full FXS single and dual-channel solutions alongside indigenously developed SLIC chips (AS1630, AS2630 series) tailored for 10G PON/FTTR devices. As the first enterprise in China to independently develop SLIC chips, the company has resolved critical industry bottlenecks, providing cost-effective subscriber line interface solutions.
A major highlight is the company’s end-to-end time-frequency synchronization solutions, which encompass a full range of crystal oscillators. Its latest ultra-low jitter differential oscillator (25MHz~625MHz, 44fs @156.25MHz) provides exceptional precision for high-performance AI devices and 5G-A/6G base stations, complemented by atomic clocks, timing modules, and clock systems for critical scenarios.
Backed by self-developed core algorithms (FPGA timing, TDC, Kalman filtering) and integrated customization capabilities, Saisi’s products are distributed in over 30 countries. This global reach reinforces its position as a significant player in China’s time-frequency sector, with its participation at MWC2026 marking a pivotal step in its global expansion.
Saisi welcomes global partners to Hall 5, Booth 5J64 to experience its products and discuss potential collaborations for AI-driven connectivity.
