SIT1573

Built on SiTime's TempFlat MEMS™ technology, this 32-kHz ±100-ppm (al-inclusive frequency stability) oscillator comes in an ultra-small 1.2mm2 chip-scale package. Typical supply current is only 4.5 μA. This device can drive 2 to 3 loads and replace multiple quartz crystals, reducing the BOM and board space. And unlike crystals, it doesn’t require external bypass capacitors.

±100 ppm all-inclusive frequency stability

• Improved local timekeeping and improved system power with less dependency on network timekeeping updates
  
• Improved system error budget
  

Smallest footprint in chip-scale package (CSP): 1.5 x 0.8 mm

• Saves board space
  

Ultra-low power: 4.5 µA (typ.)

• Maximizes battery life
  

Low jitter: 4 ns RMS integrated phase jitter (IPJ)

• Suitable for audio applications
  

Internal VDD supply filtering

• Eliminates external VDD bypass capacitor to maintain ultra-small footprint
  

Drives multiple loads

• Eliminates multiple discrete XTALs and load caps
