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.”

SiTime Unveils Next Gen Oscillators for Telecom and Networking Systems

SiTime unveiled a new family of Super-TCXOs (temperature compensated oscillators) and oscillators for telecommunications and networking equipment.


The new Elite Platform encompassing leverages the company's MEMS and analog technologies to deliver better performance, higher reliability and higher quality of service than conventional quartz solutions, even in the presence of environmental stressors.

In particular, SiTime's ELITE-Platform addresses environmental issues with potential to impact the performance of timing of network equipment in uncontrolled environments such as basements, curbsides, rooftops, and on poles. The company said precision timing components in these systems must now operate in the presence of high temperature, thermal shock, vibration and unpredictable airflow.

SiTime's Elite timing solutions are based on its unique DualMEMS architecture with TurboCompensation.

This architecture delivers exceptional dynamic performance with three key elements:

  • Robust, reliable, and proven TempFlat MEMS that eliminates activity dips and enables 30 times better vibration immunity than quartz
  • DualMEMS temperature sensing with 100% accurate thermal coupling that enables 40 times faster temperature tracking, which ensures the best performance under airflow and rapid temperature changes
  • Highly integrated mixed-signal circuits with on-chip regulators, a TDC (temperature to digital converter) and a low-noise PLL that deliver 5 times better immunity to power-supply noise, 30 uK temperature resolution that is 10 times better than quartz, and support for any frequency between 1 and 700 MHz

“New telecom infrastructure uses 4G/5G small cells and Synchronous Ethernet to increase network data capacity; the high-power components that are used in such systems will have high and constantly changing heat loads,” said Joe Madden, founder and principal analyst at Mobile Experts. “The dynamic performance of precision timing components during rapid temperature change will become a critical requirement in such equipment. MEMS technology inherently performs better in the presence of dynamic environmental conditions, and has become a very interesting alternative to quartz technology.”

The Elite Platform comprises four new product families with a wide range of frequencies and the following unique features. All Elite solutions offer 0.1 ppb/g vibration immunity and do not have activity dips or micro-jumps.

CALIENT Develops OpenDayLight Controller for Optical Switches

CALIENT Technologies introduced a software controller to facilitate dynamic reconfiguration of the optical network layer to handle the "elephant flows" typically caused by data replications, storage migrations, and movements of big data sets in Hadoop distributed file systems. These elephant flows can overflow buffers on conventional packet switches.

CALIENT said its new Optical Topology Management Controller, which built using the OpenDayLight framework, allows efficient optical topologies to be built on demand, optimizing access to compute and storage nodes to achieve maximum utilization of these critical resources.  It also lays the foundation for hybrid network fabrics in which CALIENT’s S-Series optical circuit switches augment third-party packet-based networks.

With the addition of traffic analysis and traffic engineering capabilities (planned for early 2015), the controller will support the full hybrid packet-optical network, in which the optical layer is reconfigured dynamically to create optical “express” paths that offload highly persistent traffic flows from the L2/3 packet network.

The new CALIENT controller will be used in conjunction with the company’s S-Series family of optical circuit switches. The S320 flagship is a 320-port optical circuit switch used to create an all-optical network fabric with total throughput of more than 32 terabits per second. The switch allows any-to-any, layer one network connections with almost no latency and can be reconfigured on demand under software control. Each switch port is transparent to bit rate and can support data speeds to 100 Gbps and beyond.

“We’ve seen tremendous customer interest in the powerful value proposition of the dynamically reconfigurable optical layer offered by our S-Series optical circuit switches, but the stumbling block has been the lack of a controller to allow applications and traffic patterns to drive and orchestrate the new topologies,” said Daniel Tardent, Vice President of Marketing at CALIENT. “Our new Optical Topology Management Controller is the missing link and we’re now moving ahead on a number of proof-of-concept deployments with our customers.”

The project was launched by the European Nanoelectronics Initiative Advisory Council (ENIAC) Joint Undertaking (JU), a public-private partnership in nanoelectronics.

ST said this project will also develop advanced packaging technologies and vertical interconnections using flip-chip, through-silicon vias and through-mold vias, enabling 3D-integrated devices for applications such as body area sensors and remote monitoring. A key target is to perfect a PZT deposition process compatible with mass production, and integrate it into complex MEMS processes to enable innovative actuators and sensors on System-On-Chip industrial products.
