Taitien, a leading supplier of frequency control solutions, has launched the ultra-low power consumption Disciplined Crystal Oscillator DTQ-101. DTQ-101 offers atomic clock level precision and stability while achieving miniature size and ultra-low power consumption. This series controls its internal phase error within 1 ns (RMS) by disciplining to the 1 PPS signal of the external GPS. In addition, it delivers excellent frequency output accuracy of < ± 10-12 and holdover capability reaching < ± 1.5 us within 24 hours.

DTQ-101’s typical ultra-low power consumption performance of 60 mW makes it particularly suitable for situations that require long-term use or with supply power difficulties such as underwater landform detection and oil and gas exploration. Furthermore, it is an ideal solution for portable battery-powered devices. The compact size of 39.1 x 34.0 x 14.0 mm enhances customers’ flexibility in design.

Key features:
• Ultra-low power consumption: 60 mW Typical
• Synchronization function of 1 pps input and 1 pps output
• Phase disciplined to 1 ns RMS and frequency reaching < 10-12
• Phase measurement and report system: measurable phase difference: 1 sec. with resolution reaching ≦ 1 ns
• ToD Time of Day(sec)
• 24 hours holdover < 1.5 µs
• 10 MHz, 16.384 MHz, HCMOS output
• RS232 interface

Application:
• Underwater landform detection and network system
• Telecom applications
• Low Earth Orbit Satellite
• Oil and gas exploration
• Smart grid
• Measuring equipment
• Portable battery-powered communication system

Streetlight with Public Wi-Fi

Application:
Smart Cities.

Background:
During the development of these ultra-compact replacement streetlights, the design required a connection between internal PCBs to use a horizontal spring contact for easy manufacturing.

The Challenge:
These streetlight heads add public WiFi from 4G/5G reception to communal areas – but using existing light poles means the head unit must still be compact, lightweight and self-contained, ready to install.

Harwin Solution:
By using the multi-directional spring contact in the horizontal orientation, both space and weight is saved in comparison to pogo pin connections. Board-to-board connection is fast and easy during production.

Situation:
Applications on the FA-18 fighter jet and the Cheetah M-ATV utilized ARINC connectors mated with circuit boards.

• A mechanism to provide an easier installation of dozens of discrete contacts onto a PCB was needed.
• More ruggedized contacts able to withstand the continuous exposure to high shock and vibration while offering lower insertion force were required.

Solution:
IEH engineers designed press-fit Hyperboloid Contacts encased in a pin carrier to allow a one-step installation onto a PCB. This saved assembly time and provided the uninterrupted connectivity performance associated with Hyperboloid technology, a necessity in harsh environments.

Application:
Collaborative robots for industrial platforms

Background:
Fine pitch connections required to save space on PCBs, capable of low current data signals and polarized for easy assembly.

The Challenge:
To meet space and cost criteria, with connections designed for manufacture – polarization and shrouding built in for fast, simple assembly.

Harwin Solution:
1mm pitch board-to-cable connectors, polarized and shrouded. Easy to mate, connects in only one direction.

Today’s high speed serial applications are driving increasing capacity and performance. To meet these demands designers are going to higher clock speeds and greater power densities. Both of the needs are supported by the ultra-low phase jitter OA-U series. The OA-U series may be specified at an any frequency from 100 MHz up to 175 MHz and is able to operate at temperatures up to +125°C. With typical phase jitter of 50 fs @ 156.25 MHz, the OA-U series is the ideal clock solution for high-speed serial applications such as network switching, optical communications and Storage Area Networks (SAN). The miniature 3.2 x 2.5 mm SMD package also enables more compact system designs and lower total cost.

Leveraging Taitien’s vertical integration production of quartz wafers and low phase noise oscillation circuit design technology, the newly launched OA-U series is available from 100 MHz to 175MHz with the phase jitter = 100fs rms, maximum. There are 3 logic outputs: LVPECL, LVDS and CML and the supply voltages are 2.5 V and 3.3 V. The frequency stability maybe specified as tight as ±25 ppm over -40°C to +85°C or ±50 ppm over -40°C to +125°C.

Application:
Commercial Aviation Cabins.

Background:
The customer needs cost-effective vibration-proof connections, capable of long-term endurance with many hours in-service, maintaining reliability.

The Challenge:
With long-term vibration and multiple years of service, a high-reliability connection was required with durable board fixings and easy assembly.

Harwin Solution:
Datamate J-Tek connectors fitted with board mount studs for additional strength on the PCBs. Guide pins were chosen for the mating interface to facilitate simple and fast connection at assembly.

When surgeons operate, they need 100% reliability.

EV Charging Station

Application:
External units for public parking bays.

Background:
Rugged design required for long term environmental exposure such as heat, cold and humidity. Easy maintenance also a factor.

The Challenge:
The customer needed a better solution for a long-term connection, one that would be more durable over time and with continual external temperature variations. Board-to-board spacing was also a factor.

Harwin Solution:
Archer Kontrol delivered the right level of performance and quality, capable of long-term consistent durability and cost-effective specifications – and at the right mated height.
