With a built-in MEMS resonator, SiTime’s Symphonic SiT30100 cellular clock generator replaces as much as 4 discrete timing units. It supplies correct clock indicators for 5G and GNSS chipsets in cellular and IoT units equivalent to smartphones, tablets, laptops, and asset trackers.
An built-in temperature sensor feeds exact knowledge to compensation algorithms, serving to keep clock stability. This improves GPS accuracy and reduces lock time, enabling steady efficiency even in harsh environmental circumstances.
The SiT30100 delivers 4 clock outputs at 76.8 MHz, 38.4 MHz, or 19.2 MHz—configurable from any output—for baseband, RF, and GNSS functions. By eliminating the necessity for an exterior resonator, the SiT30100 permits a compact 2.22-mm² single-chip answer. A number of Output Allow pins permit selective output management to scale back energy consumption and reduce EMI. The gadget additionally encompasses a temperature-to-digital converter with a single-wire UART interface for system-level temperature compensation, supporting frequency stability right down to ±0.5 ppm.
The Symphonic cellular clock generator is out there now in a 10-pin chip-scale package deal.
