Up to 25% Faster Wireless Charging with MEMS Timing Solution

15/10/2021

The SiT3901 is a µPower digitally controlled MEMS oscillator (DCXO) ideal for power-sensitive and space-constrained mobile and IoT applications. The SiT3901 improves wireless charging speed by up to 25% while reducing the overall timing solution area by up to 90%. The MEMS oscillator is ideal for wireless charging systems for smartwatches, activity trackers, hearing aids, and wearables.

The power and size requirements of new wireless applications demand a new approach to timing. The SiT3901 DCXO is the industry’s first µPower digitally controlled oscillator, and it delivers by improving charging efficiency and reducing the area.

Main Features

  • Ultra-low 105 micro-amps of current consumption (typical)
  • Ultra-wide digital pull range (up to 15%) for output frequency
  • Stability over temperature of ±50 and ±100 ppm
  • Wide temperature range, from -40 oC to +85 oC
  • Ultra-small 1.5 mm x 0.8 mm package size
  • Programmable frequency from 1 MHz to 26 MHz
