SiTime ships MEMS Super-TCXOs for 5G radio synchronization

SiTime announced volume production of its Elite Platform of temperature-compensated oscillators (TCXOs) that provide high stability and dynamic performance at 105°C for IEEE 1588-based synchronization in 5G/4G+ radios and enable wireless service providers to begin their network overhaul.

SiTime's Elite Super-TCXOs leverage its unique DualMEMS temperature sensing and TurboCompensation technologies. The SiT5356/7 MEMS Super-TCXOs deliver dynamic performance for timing stability in the presence of environmental stressors due to air flow, temperature changes, vibration, shock, and electromagnetic interference. The SiT5356/7 can be factory-programmed to many combinations of frequency, stability, voltage, and pull range. This programmability enables designers to optimize the clock configuration while significantly reducing the lead-time and customization costs associated with quartz TCXOs where each frequency is custom built. The device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.

“5G is expected to revolutionize the data economy but first it is re-writing the rules for wireless network deployment,” said Piyush Sevalia, executive vice president of marketing at SiTime. “5G radios will be deployed in outdoor environments – on lamp posts, buildings, traffic lights – with exposure to heat and rapid temperature changes that can cause loss of radio synchronization, which can disrupt services like advanced driver assistance systems and telemedicine. Unlike other timing vendors, SiTime takes a systems approach to solve these problems. We optimize our SiT5356/7 Super-TCXO system of MEMS, analog, advanced packaging and temperature compensation to deliver industry-leading performance of ±100 ppb stability and ±1 ppb/°C frequency slope (ΔF/ΔT) over -40°C to 105°C. We believe that radios with SiTime’s Super-TCXOs will minimize disruptions to 5G/4G+ services and ensure a better user experience.”

In June 2014, 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

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."
