SiT5008 Low-power Silicon MEMS TCXO Oscillator for Connected Consumers and IoT devices

SiT5008 Low-Power Silicon MEMS TCXO Oscillator

The new low-power MEMS TCXO oscillator, SiT5008 from SiTime Corporation is ideal for connected consumer and IoT devices such as Internet-connected audio-video, over-the-top streaming devices, industrial smart meters, and other devices that use low power wireless connectivity. Housed in a 2.5 x 2.0 mm small package that is pin-compatible with quartz devices, this new device enables 100% drop-in replacement without redesign or layout changes.


The LVCMOS SiT5008 MEMS Oscillator improves frequency stability by 10 times by optimizing the algorithms, providing a frequency stability range of +/-2 ppm to +/-10 ppm. It offers frequencies between 10 MHz and 60 MHz accurate to six decimals, supply voltages of 1.8 V, 2.8 V, and 3.3 V, and low-power consumption of 3.5 mA typical at 1.8 V. This silicon MEMS-based TCXO provides higher reliability and great vibration and shock environmental resilience. 


Key Features of SiT5008 TCXO

  • Frequency from 10 MHz to 60 MHz
  • Three supply voltage options: 1.8V, 2.8V, and 3.3V
  • Frequency stability options: ±2 ppm or ±10 ppm
  • FlexEdge programmable drive strength optimizes the clock rise/fall time for specific applications
  • Industry-best vibration and shock resilience
  • Low Power: 3.5 mA typical at 1.8V and standby mode option for longer battery life
  • Small industry-standard package
  • 100% drop-in replacement for quartz TCXOs
  • RoHS and REACH compliant, Pb-free, Halogen-free, and Antimony-free


The compact SiT5008 low power ±2 ppm MEMS TCXO is available in production now.
