As temperatures rise and the sun beats down on technology, it’s not only people who feel the heat – electronic components must also perform at their best. Frequency control products, such as quartz crystals and oscillators, are particularly critical in this regard. They ensure precise timing in countless applications – from GPS and Wi-Fi to industrial electronics. But how do these frequency products behave in heat? And what solutions does Jauch offer for demanding thermal environments?
1. JT11 Series: Miniaturized TCXOs for high frequency stability
The JT11 product family from Jauch comprises temperature-compensated crystal oscillators (TCXOs) specially developed for applications with demanding temperature requirements.
Technical highlights:
- Temperature range: -40 °C to +85 °C
- Frequency stability: up to ±0.5 ppm
- Frequency range: 13.0 – 52.0 MHz
- Package size: 1.6 x 1.2 mm (ideal for space-critical designs)
- Typical applications: WiMAX, LTE, GNSS (GPS), Wi-Fi
Special Feature:
The JT11LE variant is optimized for low-power applications. Thanks to the stop function, power consumption can be reduced to just a few µA – perfect for battery-operated devices.
2. 32.768 kHz Oscillators with AT-Cut
For particularly temperature-stable timekeeping, Jauch offers the JO22 and JO32 oscillators featuring AT-cut quartz disk. These components operate at a frequency of 32.768 kHz – the standard value for real-time clock (RTC) applications, as it can be easily converted into seconds (2¹⁵ = 32,768).
Advantages:
- Low frequency deviation with temperature fluctuations
- Temperature range: -40 °C to +85 °C
- CMOS-compatible output
- Ideal for: Wearables, medical technology, IoT
Why AT-cut?
This specialised cutting technique significantly reduces the temperature-related frequency drift compared to classic watch crystals, ensuring reliable timekeeping – even in the summer heat.
3. JOH21, JOD21, JOE21: Differential oscillators for high-speed applications
These miniature oscillators with differential output (HCSL, LVDS, (LV)PECL) are designed for high data rate applications – such as those found in data centres or telecommunications.
Features:
- Lowest phase jitter
- High temperature stability
- Ideal for: Ethernet, SDH/SONET, optical modules, IoT
Summer-proof, even with a flood of data. These oscillators provide reliable timing – even when temperatures rise.
4. Quartz crystals for extreme temperatures up to 125 °C (150 °C)
When things get really hot – whether under the hood or within industrial control systems – you need components that are not only precise but also extremely robust. Jauch offers a range of AEC-Q200-tested quartz crystals specifically developed for use in automotive technology and for demanding industrial applications.
Technical features:
- Temperature range: up to +125 °C (JXS32P4 with 3.2 x 2.5mm package, supports up to +150°C)
- Tested according to AEC-Q200 – the automotive quality standard for passive components
- Frequency ranges: from 8 MHz to 60 MHz (depending on model)
- Housing sizes: e.g. 1.6 x 1.2 mm, 2.0 x 1.6 mm, 2.5 x 2.0 mm, 3.2 x 2.5 mm
- Typical applications: Engine control units, sensors, infotainment, ADAS
Why this matters:
Temperature-related frequency deviations can have fatal consequences in safety-critical applications. Jauch’s automotive-grade crystals are engineered to deliver reliable performance even under continuous load in hot environments – with minimal frequency drift.
Conclusion:
Whether miniature TCXOs for GPS trackers, temperature-stable oscillators for medical technology, differential frequency products for high-speed communications, or automotive crystals for extreme temperatures – Jauch offers the right frequency component for every summer challenge. This ensures your design stays cool and precise, even at 85 °C.
