SiTime Corporation introduces the SiT3901 µPower digitally controlled MEMS oscillator (DCXO) targeting power-sensitive and space-constrained mobile and IoT applications.
The SiT3901 is said to improve the wireless charging speed by up to 25% while reducing the overall timing solution area by up to 90%. Wireless charging standards such as Qi rely on resonant power transfer to enable proximity charging. However, environmental interference may dynamically impact the resonant charging frequency. To tackle this issue, SiT3901 dynamically tunes the resonant frequency, maximizing power transfer and delivering up to 25% faster charging.
The SiT3901 DCXO features digital control that eliminates the need for additional passive components on the board, reducing the timing solution area by up to 90%. It consume up to 90% less power compared to quartz oscillators, enabling environmentally friendly electronics. It features a wide digital pull range (up to 15%) for output frequency and programmable frequency from 1 MHz to 26 MHz.
