SiTime debuts MEMS-based oscillators for wireless infrastructure

SiTime introduced a new precision timing platform for wireless infrastructure including radios in small cells, remote radio units (RRUs), microwave backhaul, and SATCOM equipment. 

The new SiTime Elite RF Super-TCXO is an entirely new class of MEMS-based temperature-controlled oscillators designedto withstand extreme environments in which 5G radios are deployed, while delivering the phase noise, accuracy, and resilience in a single, highly integrated device. 

SiTime said its new devices also meet the stringent performance requirements specified by the IEEE 1588v2 timing synchronization protocol.

Until now, mini-OCXOs were the primary timing reference for 5G and SATCOM radios. Mini-OCXOs provided the stability over changing temperature that was necessary to clock advanced synchronized radios. While mini-OCXOs are accurate, they are notoriously unreliable, especially in harsh environments, and they consume excessive power and board space and require additional components, such as jitter cleaners and VCXOs for generating RF-capable clocks. One Elite RF Super-TCXO replaces all these components.

“To enable new services, radios are expected to deliver 10x the bandwidth of previous generations with significantly lower latency,” said Piyush Sevalia, executive VP of marketing, SiTime. “To achieve these performance goals, next-gen radios must be deployed closer to the user, and all nodes in the network must be time-synchronized. Past radio architectures used separate timing devices for the radio and for synchronization. The SiTime Elite RF platform integrates these two clocking functions, simplifying the radio timing architecture and delivering on the promise of 5G bandwidth and coverage.”

Elite RF Super-TCXO Family Highlights

• 1 to 220 MHz any frequency output
• ±100 ppb stability over temperature
• -40 °C to +105 °C operating temperature range
• ±0.9 ppb/°C stability over temperature slope

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.”
