SiTime Corp. has unveiled its first mobile clock generator with an integrated microelectromechanical systems (MEMS) resonator.
Called the SiT30100 provides clock signals for 5G and GNSS chipsets for efficient power consumption in mobile and internet of things (IoT) devices like smartphones, tablets, laptops and asset trackers.
“Every generation of mobile devices becomes smarter, delivering greater functionality, personalization 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.”
SiTime said the integrated MEMS resonator inside the clock generator provides functionality of up to four discrete timing devices. The company said this reduces space on a board and simplifies design while providing data sensing information that is used by compensation algorithms for stability.
Additionally, it will allow better GPSD accuracy and faster lock time at the system level.
Other features of the MEMS IC include:
- Four-output clock generator
- Integrated MEMS resonator
- Integrated high-precision temperature-to-digital converter (TDC) with single-wire universal asynchronous receiver/transmitter (UART) interface
- Multiple output enables pins to turn on and off individual clock outputs
- -30° C to 90° C operating temperature range
