32khz

SiTime's SiT15xx MEMS-based 32 kHz oscillator family is ideal for replacing traditional quartz crystals (resonators) in mobile applications where space and power are critical. 

  • aceawards2014World's smallest footprint: 1.5 x 0.8 mm CSP
  • XTAL replacement in 2.0 x 1.2 mm SMD
  • Ultra-low power: 750nA (typ)
  • NanoDrive™ output minimizes output power
  • Low-voltage operation:
    • SiT153x: Optimized for regulated supply apps: 1.2V to 3.63V
    • SiT154x: Optimized for unregulated Li+ battery apps: 2.7V to 4.5V
  • Oscillator output eliminates external load caps
  • Internal filtering eliminates external Vdd bypass cap
  • < 20 PPM initial stability at RT, < 100 PPM stability over -40°C to +85°C
