Mobile Clock Generator Advances Wireless Connectivity
SiTime recently released the Symphonic SiT30100 mobile clock generator, which includes an integrated MEMS resonator. Providing accurate and resilient clock signals for 5G and GNSS chipsets, the device enables efficient power consumption in IoT products.
The clock generator can withstand thermal and mechanical stressors caused by increasing processing and connectivity speeds, delivering the precision timing required for advanced connectivity of next-generation mobile devices.
Equipped with the MEMS resonator, the 2.22-mm2 Symphonic clock generator offers the functionality of up to four discrete timing devices, simplifying system design and reducing space on the board. Its integrated temperature sensor delivers accurate timing with superior stability, enabling better GPS accuracy and faster lock time for more stable performance under harsh environmental conditions.
The four-output clock generator provides 76.8, 38.4, or 19.2 MHz from any output for baseband, RF, and GNSS applications, a frequency stability as low as ±0.5 ppm, and a –30 to +90°C operating temperature range. Custom wider temperature range versions are available. Multiple output-enable pins can turn on and off the clock outputs for system power optimization and EMI reduction.
