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.

Microsoft Azure Accelerates its Networking Capabilities

Microsoft rolled out a number networking capabilities for its Azure cloud service, including advancements to its global server fleet that the company says will improve networking bandwidth performance 33% to 50%.

The improvements include hardware technologies such as NVGRE offload, which harnesses the network processing capabilities of the hardware. Windows and Linux VMs will experience these performance improvements while returning valuable CPU cycles to the application.

Microsoft said its Accelerated Networking provides up to 25 Gbps of throughput and drastically reduces network latency up to 10x.

The new hardware technologies including SR-IOV, which allows VMs to communicate directly to the hardware NIC completely bypassing the Hypervisor’s virtual switch, bringing higher bandwidths and lower latencies, along with reduced jitter and improved Packets Per Second (PPS) performance. With Accelerated Networking, Azure SQL DB In-Memory OLTP transaction performance improved 1.5X.

Additional highlights:

  • Azure Storage users will benefit from substantially increased IOPS performance based on these advancements, combined with newly developed storage specific offloads. Hardware now efficiently performs data transfers up to the line rate of the NIC. The roll out for Storage will also complete in 2016.
  • General availability of Virtual Network Peering (VNet Peering), which connects Virtual Networks (VNets) in the same region, enabling direct full mesh connectivity. VMs in the peered VNets communicate with each other as if they are part of the same VNet, thus benefiting from high bandwidth and low latency. Hub & Spoke topologies are supported with Transit Routing through gateways. The VNet without a gateway still has cross-premises connectivity via the gateway in the peered VNet. VNet Peering works across subscriptions allowing for simplified service management.
  • New UltraPerformance Gateway SKU for ExpressRoute that supports up to 10 Gbps throughput. This is a 5x improvement over the existing ExpressRoute HighPerformance gateway with a 99.95% availability SLA.

Nokia Intros Gainspeed Platform for Unified Cable Access

Nokia introduced its new Gainspeed portfolio for unified cable access, supporting all cable access networks including hybrid fiber-coaxial (HFC), passive optical networking (PON) and point-to-point Ethernet.

Nokia said its new platform takes a software-defined Virtualized Converged Cable Access Platform (CCAP) approach that provides the capacity, agility and flexibility cable operators need to deliver new revenue-generating services while significantly reducing operating expenses.

The architecture pushes cable-specific functions out to access nodes close to the subscriber while centralizing control and management. This approach significantly reduces the costs of traditional cable architectures by eliminating the CCAP as a physical box and replacing the analog optical transmission with 10Gbps Ethernet.

"The cable industry is at a crossroads and facing change at a level it has never seen before. The current way of building cable networks simply will not scale to meet the tidal wave of IP video and high-speed data demands faced by cable operators. We're helping operators add capacity, greatly simplify the network operations and prepare for an all-fiber, all-IP network," stated Jeff White, head of business development and strategy for cable in Nokia's Fixed Networks business group.

The new Nokia portfolio of cable access products includes:


  • Gainspeed Access Controller
  • Gainspeed Video Engine
  • Gainspeed Access Node SC-2D supporting DOCSIS 3.0 and 3.1
  • Gainspeed Access Node SF-4X supporting 10G EPON


The company said lab and field trials are underway.

Nokia to Acquire Gainspeed for Virtualized Cable Architecture

Nokia agreed to acquire Gainspeed, a start-up specializing in DAA (Distributed Access Architecture) solutions for the cable industry via its Virtual CCAP (Converged Cable Access Platform) product line. Financial terms were not disclosed.

Gainspeed's Virtual CCAP enables cable operators to increase the capacity of their existing HFC (Hybrid Fiber Coax) infrastructure and rapidly deploy new services, while simultaneously reducing space and power requirements in the headend. The solution also enables cable operators to migrate their networks to a software-driven, all-IP architecture.

Gainspeed's design eliminates the physical CCAP by leveraging SDN and NFV to distribute the CCAP’s functions to other devices and locations in the network. This centralizes routing, control and management in the data center or cloud and pushes
the physical layer, DOCSIS processing and RF modulation into the node, deep within
the access network

Gainspeed is based in Sunnyvale, California and has approximately 70 employees.

Federico Guillen, president of Nokia's Fixed Networks business group, said: "We are very excited to have Gainspeed, the technology leader in its field, joining us. Cable is one of the fastest growing areas in our fixed networks business, and we are committed to delivering a complete solution set to cable operators. Gainspeed's Virtual CCAP perfectly complements our leading fiber access solutions for cable MSOs."
