Clock generator boosts GPS accuracy
With a built-in MEMS resonator, SiTime’s Symphonic SiT30100 mobile clock generator replaces up to four discrete timing devices. It provides accurate clock signals for 5G and GNSS chipsets in mobile and IoT devices such as smartphones, tablets, laptops, and asset trackers.
An integrated temperature sensor feeds precise data to compensation algorithms, helping maintain clock stability. This improves GPS accuracy and reduces lock time, enabling stable performance even in harsh environmental conditions.
The SiT30100 delivers four clock outputs at 76.8 MHz, 38.4 MHz, or 19.2 MHz—configurable from any output—for baseband, RF, and GNSS applications. By eliminating the need for an external resonator, the SiT30100 enables a compact 2.22-mm² single-chip solution. Multiple Output Enable pins allow selective output control to reduce power consumption and minimize EMI. The device also features a temperature-to-digital converter with a single-wire UART interface for system-level temperature compensation, supporting frequency stability down to ±0.5 ppm.
The Symphonic mobile clock generator is available now in a 10-pin chip-scale package.
