SiTime, Silicon MEMS Oscillators and Clock Generators

LVCMOS/LVTTL Compatible Oscillators

E-mail Print

SiTime's ultra performance oscillators deliver 0.6 ps phase jitter (12 kHz to 20 MHz) and ±10ppm stability. These devices are the first MEMS timing solutions to exceed the stringent SONET clocking requirements, and are ideal for applications in telecom, networking and storage. They are 100% drop-in replacements for crystal oscillators and third-overtone oscillators.

They support:

  • Frequencies from 1 MHz to 220 MHz with 6 decimal places of accuracy
  • 1.8V, 2.5V to 3.3V operation
  • Industry standard footprints – 2520, 3225, 5032 and 7050 packages
  • Industrial and extended commercial temperature ranges
