SIT1580

SiTime's TempFlat MEMS™ technology, coupled with our mixed-signal capability, enables the smallest 32-kHz TCXO in a 1.2mm² chip-scale package. These devices use MEMS resonators that are manufactured using the latest generation of EpiSeal™ technology which hermetically seals the resonator, making it impervious to all small-molecule gases. Additionally, the SiT1580 has a high shock and vibration survivability. These TCXOs are factory calibrated over multiple temperature points to guarantee extremely tight ±5 ppm all-inclusive frequency stability. Typical core supply current is only 4.5 μA.

Smallest footprint in chip-scale (CSP) 

• 1.5 x 0.8 mm: Saves board space
  

Ultra-low power: 4.5 µA (typ)

• Maximizes battery life
  

Low jitter 2.5 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 + load caps
  

Robust against shock, vibration, and small molecule gases
