SiTime Brings MEMS Timing to Wearables

SiTime introduced the smallest, lowest power 32 kHz TCXO (temperature compensated oscillator) designed for the emerging market of wearable electronics and Internet of Things (IoT).

The new, 32 kHz TCXO (temperature compensated oscillator) device, which leverages SiTime's MEMS technology, comes in a 1.5 x 0.8 mm chip scale package (CSP). It can perform various functions in a system included delivering reference for real time clock (RTC) function, sleep clock for connectivity (Bluetooth, Bluetooth Low Energy, Wi-Fi), and heartbeat clock for battery supervisory function.

Compared to a quartz TCXO, the SiT1552 MEMS TCXO is:

  • 20% of the size and is available in a 1.5 x 0.8mm CSP
  • 50% lower power, typically consuming less than 1 micro-amp
  • 45% thinner, with a height of 0.55 mm
  • 10 times faster startup, with a startup time of 0.3 milliseconds
  • 30 times higher shock resistance
  • 15 times higher reliability, at 500 million hours MTBF

“By using its game-changing TempFlat MEMS and analog technology, SiTime has once again shattered the limitations of quartz. The SiT1552 MEMS TCXO is 20% of the size and consumes 50% of the power of comparable quartz devices,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Our MEMS enable new system architectures that offer higher performance, small size and longer battery life. With another industry first, we continue to revolutionize the timing industry with our breakthrough MEMS solutions.”
