1 Hz to 1 MHz XO/TCXOs

1 Hz to 1 MHz XO/TCXOs

 

SiTime’s MEMS-based 1 Hz to 1 MHz oscillator solutions are ultra-small, low-power, low-frequency reference sources that provide a new level architectural options in wearable, mobile, and IoT applications where space and power are critical.

 

  • World’s smallest footprint: 1.5 x 0.8 mm CSP
  • XTAL replacement in 2.0 x 1.2 mm SMD
  • Ultra-low power: <1 – 4.5 μA
  • 5 PPM all-inclusive frequency stability (SiT1576)
  • Super-TCXO maintains stability in presence of significant temperature gradients in excess of 10°C/sec (SiT1576)
  • NanoDrive™ output (SiT1534) minimizes output power
  • Oscillator output eliminates external load caps
  • Oscillator output drives multiple loads and replaces multiple XTALs
  • Internal filtering eliminates external Vdd bypass caps
  • Best XO and TCXO frequency stability:
    – SiT1534 1 Hz – 32.768kHz XO: <75 to 100 PPM over temperature
    –  SiT1576 1Hz to 1 MHz TCXO: <5 PPM all-inclusive stability, 2.5ns RMS Integrated Phase Jitter (IPJ)
