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.”

SiTime Extends Lifetime Warranty for MEMS Timing Devices

In a testament to the durability of its MEMS oscillators and clock generators, SiTime has decided to extend a lifetime warranty that the devices will conform to specifications for the life of the system.

“Since 2007, SiTime has shipped 200 million units of our silicon MEMS timing solutions with zero MEMS failures. The outstanding quality and reliability of SiTime’s products is due to two unique factors – single crystal silicon material and the EpiSeal manufacturing process. Unlike other manufacturers who use poly crystalline silicon and oxides, SiTime constructs the MEMS resonator from pure single crystal silicon, which ensures that the performance of the resonator does not change with time. The EpiSeal process anneals the MEMS resonator and encapsulates it in a perfectly clean vacuum for maximum durability and reliability,” said Piyush Sevalia, executive vice president of marketing at SiTime. “SiTime’s reliability is two orders of magnitude, 100 times better than quartz."

SiTime Introduces TempFlat Technology for MEMS Oscillators

SiTime introduced TempFlat MEMS technology -- an ability to eliminate temperature compensation in precision timing applications, resulting in higher performance, smaller size, lower power and cost.

TempFlat MEMS technology is being used in SiTime’s SiT15xx family of kHz oscillators for Smartphones.  The devices are currently available.

“In 2006, our semiconductor process enabled the first production MEMS oscillator. Since then, we have had many firsts – we introduced a MEMS TCXO, a MEMS oscillator with 500 femtoseconds of jitter, and a clock generator with integrated MEMS – all of which are used in consumer, industrial and cloud applications. Most recently, we entered the fast-growing smartphone market with our TempFlat MEMS-based 32 kHz oscillators,” said Rajesh Vashist, CEO of SiTime. “In 2011, SiTime demonstrated 100 PPB (parts per billion) stability with our high-performance temperature compensation. With TempFlat MEMS, which is 30 times better than SiTime’s prior resonators, we can get to 5 PPB oscillators for Stratum 3E timing in base stations, small cells and optical networking. SiTime is now uniquely able to service all segments of the electronics industry.”
