SiTime Delivers Timing Products for 5G Radio Synchronization in Global Wireless Network

Sponsored by Businesswire

, a market leader in MEMS-based silicon timing system
solutions, announced volume production of its award-winning 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.

“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

Meeting 5G’s Tougher Timing Requirements

Radio synchronization is a crucial technology that enables 5G and 4G+ to
maintain service quality and reliability. The use of eCPRI and
distributed architectures in 5G and 4G+ networks, along with outdoor
deployment, increases timing complexity for synchronization.

Elite Super-TCXOs

Leveraging SiTime’s 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.


Samples and production volume of Elite Platform Super-TCXOs are
available now. Pricing is available upon request.
