Application:
Location and Temperature reporting from Servo Motors.

Background:
Encoders are an important part of modern servo motors, ensuring that the control system obtains high resolution feedback from the motor operation. This includes positioning and health status.

The Challenge:
With the reducing size of space envelopes for motors, the encoder must also be minimized. The internal connectors must be robust to withstand a variety of demanding environments. For improvements in automated manufacture, the terminations need to be shorter for use with Pin-In-Hole reflow (PIHR) solder processes and delivered in tape-and-reel packaging.

Harwin Solution:
The Datamate L-Tek range now includes 2- and 3-contact male PCB connectors with 2mm terminations, suitable for PIHR processing. These connectors are packaged in tape-and-reel. By using the Datamate L-Tek design as a base, these connectors are already compact, robust, and proven in challenging applications.

Product Applications

LSR parts are not only for water proof and shockproof function, they can also be utilized as key structure for acoustic performance.

Taitien has been manufacturing quartz frequency control products for consumer electronics and high-end applications since 1976. Forty years on, the Taiwan-based company has expanded its operations worldwide, boasting manufacturing facilities across Taiwan, the US, and China.

Regularly named among the top five-thousand large scale enterprises in Taiwan, it’s no surprise that Taitien has built a reputation as a leader in the quartz industry given that it is the first in Taiwan who possessed the capability and production capacity in manufacturing their own quartz bars and High-Frequency Fundamental (HFF) inverted-mesa blanks.

With over twenty invention patents to its name, the company remains dedicated to research and development, investing around 4.4% of its revenue back into new technologies. Such an approach will no doubt prove crucial to meeting the new technical threshold for ultra-precise frequency controls that’s emerged during the race to 5G.

The Importance of Frequency Controls
Frequency control is a fundamental part of most electronic products. In crystal oscillators, quartz removes noise and stabilizes the frequency as it transmits a signal, thereby improving the accuracy of timekeeping, positioning, and navigating.

They can therefore be used across a vast range of applications, from high-end applications in aerospace to regular consumer electronics, like clocks and phones. Taitien points to wireless, wired, data centers, and industrial/consumer as four main application areas of quartz components. Hence, it’s vital that companies producing frequency control products have access to vast quantities of it.

Taitien claims to be the pioneer in Taiwan possessing the technology to produce their own quartz. ‘We are one of the two leading companies in the world – following Epson – that possesses the photolithography technology used to produce HFF inverted-mesa blanks,’ says C.Y. Teng, Director of R&D at Taitien.

What Kind of Products does Taitien Offer?

Timing Modules
Among Taitien’s most popular products are its timing modules, which includes the DT-6565. Using GPS Disciplined Oscillators to ensure accuracy down to the nanosecond, these modules can be used for timekeeping and positioning in many different contexts – be it in radars, satellites, or critical infrastructure.

The DT-6565 is remarkable because its timekeeping capabilities are almost identical to that of an atomic clock, with a holdover performance of 1.5us over twenty-four hours. This greatly outperforms the industry standard for similar-sized timing modules.

OCXO
Oven Controlled Crystal Oscillators heat quartz in an ‘oven’, protecting the crystal from external changes in temperature, gravity, and vibration. This ensures that the frequency and performance of the oscillator is both highly stable and accurate.

As a result of their continued research into environmental resistance, Taitien’s OCXOs have an exceptionally low aging rate of just 0.2 ppm a year, while the phase noise floor (which can reach -180dBc/Hz) is far lower than competing products.

With 5G here to stay, the demand for OCXO is on the rise; to operate a small 5G base station currently requires at least one OCXO, while a larger station could require more than ten. Given that Taitien is currently one of the only OCXO manufacturers in Asia (accounting for over 3% of the OCXO global market share), the company looks to benefit massively from the race to 5G. ‘Our OCXOs are largely used in network communication for large base stations – customers include well-known manufacturers like NSN and Huawei,’ says C.Y. Teng.

Maneuvering the Pandemic, Looking to the Future Unlike most companies, Taitien claims that due to the COVID-19 the demand for its products has increased. ‘Our supply chain was well-prepared even before the pandemic, while many of our competitors were unprepared to take orders,’ says C.Y. Teng. Between the pandemic and the onset of 5G, business is booming. It looks set to stay that way.

‘The arrival of 5G and the rise of AIoT has greatly shifted the technical threshold when it comes to quartz frequency control products. These new ventures require higher precision and higher environmental resistance, which our quartz-based frequency control products can provide. Maintaining production capacity to meet these new technical requirements will be key to ensuring continued success.’

With the advantages of low power consumption, small size, and high precision, they can be widely used in wearable devices and the Internet of Things field.

For applications requiring low power consumption, the choice of crystals is critical.  TAITIEN ‘s newly launched ultra-low current crystal oscillators feature current consumption that is less than 1.4μA and can run on an ultra-low voltage of 1.5V. The low current represents a significant decrease in current consumption of more than 90% from the 32.768kHz oscillators used in the past. This offers a significant improvement in the applications power consumption and battery life. These performance improvements are the result of an exclusive patented circuit design that only needs 8ms to start up. The rise and fall times of the output signal is a fast 10ns, satisfying the signal requirements of most end equipment.

The 32.768kHz clock signal provided by TAITIEN’s ultra-low current OZ-D and OY-D oscillators can fully support the Real Time Clock (RTC) function todays MCUs or ICs the require an external reference clock with low power. The OZ-D and OY-D oscillators use AT-cut crystal units with high Q values that were specifically designed for this product as the frequency reference source. The AT-cut crystals enable the oscillators to provide superior frequency stability then the traditional oscillators used in the past. For wide temperature such as -40°C to +85°C, the frequency error will not exceed ±25ppm. The crystals also results in low aging rate of less than ±3ppm, in the first year another way the they enable a long product life cycle.

Another advantage of these oscillators is their small size which is a must for todays’ IoT, wearable and other low-power applications. TAITIEN’s ultra-low current crystal oscillators are available in two sizes, The OY-D which is 2.5 x 2mm and the OZ-D which is only 2 x 1.6mm, providing a high degree of flexibility for system design and facilitating the miniaturization of products with a compact space structure.

TAITIEN’s ultra-low current OZ-D and OY-D oscillators feature low power consumption, small size, and high precision making them a great choice for Smart Phones, Fitness Watches, Sport Video Cams, Ultra-Small Notebook PC, Wireless Keypads, RTC Reference Clock, Battery Management Timekeeping, Pulse-per-second(pps) Timekeeping, Wearables, IoT, GPS, Home Automation and Smart Metering.
