SiTime recently announced Symphonic, its first mobile clock generator with an integrated MEMS resonator (SiT30100). Symphonic provides accurate and resilient clock signals for 5G and GNSS chipsets and facilitates efficient power consumption in mobile and IoT devices such as smartphones, tablets, laptops, and asset trackers. This product unlocks a cumulative $2 billion served addressable market (SAM) in the next five years.
“Every generation of mobile devices becomes smarter, delivering greater functionality, personalisation and automation,” said Rajesh Vashist, CEO and Chairman of SiTime. “Timing devices must withstand thermal and mechanical stressors as processing and connectivity speeds increase. Our newest mobile clock generator delivers the precision timing required for advanced connectivity of next-generation mobile devices.”
The Symphonic clock generator features an integrated MEMS resonator and provides the functionality of up to four discrete timing devices. This approach simplifies system design, subsequently reducing space on the board. An integrated temperature sensor delivers accurate information that is used by compensation algorithms to provide superior stability. This enables better GPS accuracy and faster lock time at the system level, delivering a more stable performance under harsh environmental conditions.
“Ensuring that wireless and GPS protocol-dependent systems and services run reliably is essential for meeting the requirements of increasingly sophisticated wireless devices and use cases,” said Dave Altavilla, President and Principal Analyst, 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.”
The key features of the SiT30100 are as follows:
- 4-output clock generator providing 76.8MHz, 38.4MHz or 19.2MHz from any output for baseband, RF and GNSS applications
- Integrated MEMS resonator, which eliminates an external resonator, and provides a smaller, single-chip solution which is only 2.22 mm2 in area
- Integrated high-precision temperature-to-digital converter (TDC) with single-wire Universal Asynchronous Receiver/Transmitter (UART) interface for system-level temperature compensation to achieve frequency stability as low as ±0.5ppm
- Superior performance and dynamic stability under airflow and thermal shock
- Multiple Output Enable pins to turn on and off clock outputs for system power optimization and electromagnetic interference (EMI) reduction
- -30°C to +90°C operating temperature range (contact SiTime for wider temperature ranges)
