SiTime’s SiT3901 digitally-controlled MEMS oscillator improves wireless charging speed by up to 25%, while reducing the timing solution area by 90%.
SiTime has introduced the SiT3901 µPower digitally-controlled MEMS oscillator (DCXO) that claims to enable up to 25% faster wireless charging, while reducing the timing solution area by 90%. Targeting power-sensitive and space-constrained mobile and IoT applications, the DCXO, housed in an ultra-small 1.5 × 0.8-mm package, is suited for wireless charging systems for smartwatches, activity trackers, hearing aids, and wearables.
“Wireless charging standards such as Qi and AirFuel rely on resonant power transfer to enable proximity charging,” said SiTime. “However, environmental interference may dynamically impact the resonant charging frequency, which slows down the charging process.”
