SiTime's MEMS-based 32 kHz and 1 Hz-1 MHz XO and TCXO solutions are ideal for replacing traditional quartz crystals (resonators) in wearable and mobile applications where space and power are critical. 

  • aceawards2014World's smallest footprint: 1.5 x 0.8 mm CSP (SiT1532)
  • XTAL replacement in 2.0 x 1.2 mm SMD
  • Ultra-low power: <1 μA
  • NanoDrive™ output minimizes output power
  • 1.2V operation optimized for regulated supply applications such as coin-cell or super-cap battery backup
  • Oscillator output eliminates external load caps
  • Oscillator output drives multiple loads and eliminates multiple XTALs
  • Internal filtering eliminates external Vdd bypass cap
  • Best uncompensated frequency stability: 10-20 PPM initial offset, 75-100 PPM over temp stability
