Development of the world’s smallest industry-leading low g-Sensitive*1temperature-compensated crystal oscillator

Nihon Dempa Kogyo (NDK) has begun shipping samples of its new vibration-insensitive, low
g-sensitive*1 temperature-compensated crystal oscillator. The two models – a compact type (2.0 ×1.6 × 0.7 mm) and a high-precision type supporting Stratum 3 and ITU-T TR-G8262 application(3.2 × 2.5 × 1.1 mm) – the vibration sensitivity performance are 10 times better than conventionaloscillators.
Recent remarkable advances in areas of information and telecommunications such as 5G/LTE
high-speed communications, 4K/8K video communications, car telecommunication devices andIoT, have created increasing demands for support from highly stable, high-quality oscillators.
However, there is a need to address vibration associated with various outdoor operation
environments, cooling fans, drones used with communication devices and other sources that may
affect oscillators during system usage and impair telecommunication quality. In relation to thevarious telecommunication systems available, effects on rapidly evolving multilevel modulation
systems*2 are of particular concern.
To address these needs, NDK has developed a new oscillator with superior anti-vibration
performance using photolithographic technology and stress analysis simulation.
This product provides low g-sensitivity of 0.1 ppb/G, which is among the lowest in the industry
and over 10 times better than conventional temperature-compensated oscillators of the same size.
It offers clear superiority over the performance of MEMS oscillators, and supports high-stability,
high-quality performance of devices in a wide range of environments.
NDK remains committed to its development efforts in the field of high-quality, high-speed
communications based on the broad application of this technology to oscillators and other crystaldevices.
*1: Low g-sensitivity
Low acceleration sensitivity expressed as frequency change per unit of gravity acceleration*2: Multilevel modulation system
A modem application in which data is associated with radio waves or electrical signals basedon phase and amplitude. Used in LTE mobile communications, Wi-Fi, optical communications
and other fields. The system allows transmission of high volumes of information with superior
efficiency, but is sensitive to noise.
