Product Spotlight: A New, Smarter Clock Generator for 5G and GNSS Design Challenges
Designing for today’s mobile and connected devices means meeting high expectations — not just in performance, but in size, power efficiency and environmental resilience. As data speeds rise and applications become more demanding, timing solutions must keep pace. That’s where SiTime’s Symphonic™ mobile clock generator (SiT30100) comes in.
This is SiTime’s first mobile-focused clock generator, and it’s engineered with integration and reliability in mind. Built around a MEMS resonator, the Symphonic clock generator combines high performance and low power in a compact 2.22 mm² footprint — making it ideal for smartphones, tablets, laptops, wearables and industrial asset trackers.
Why It Matters for Your Design
Precision timing is the backbone of wireless and GNSS-enabled systems — it ensures everything from baseband processing to RF and satellite sync runs smoothly. The Symphonic clock generator reduces timing uncertainty, simplifies system architecture and enhances resilience in thermally and mechanically demanding environments.
According to Dave Altavilla, president and principal analyst at HotTech Vision & Analysis, “SiTime’s new clock generator is an example of how precision timing technology is a critical enabler of AI-first mobile experiences.”
What Makes the Symphonic Clock Generator Stand Out?
-
Single-Chip Integration
Combines the functionality of up to four timing devices — saving board space and BOM complexity.
-
Flexible Output Configuration
Supports 76.8 MHz, 38.4 MHz or 19.2 MHz on any of the four outputs — ideal for baseband, RF and GNSS applications.
-
Built-In MEMS Resonator
No external resonator required — reduces system size and improves shock/vibration resilience.
-
High-Precision Temp Compensation
Integrated temperature-to-digital converter (TDC) feeds compensation algorithms to deliver system stability as tight as ±0.5 ppm, improving GNSS lock times and location accuracy.
-
Smart Power and EMI Management
Individual output enable pins that let you power down unused clocks, reducing overall system power and electromagnetic interference (EMI).
-
Engineered for Real-World Conditions
Maintains performance across –30°C to +90°C with strong resilience to airflow and thermal shock.
The Bigger Picture
As technology advances, driven by AI, the Symphonic clock generator is built to support this shift. Precision timing is a critical enabler—offering designers a practical path to highly resilient wireless performance.
