PETERMANN-TECHNIK supplies the most comprehensive product range of low cost high performance 32.768 kHz solutions. The product range includes crystals, crystal oscillators, ultra low power silicon oscillators and RTCs.
The 32.768 kHz crystals are available with frequency tolerances at 25°C from ±10 to ±20ppm in the standard temperature range of -40/+ 85°C. Automotive solutions based on AECQ200 or AECQ100 are available on request.
The 32.768 kHz MICRO-SMD silicon oscillators are predestined for use in battery-powered solutions such as Bluetooth Low Energy, IoT, wearables, RTCs, mobile communication, smart metering, smart housing, consumer, medical and industrial applications, etc. and offer excellent performance data and very favourable prices. The 2.0x1.2mm MICRO-SMD silicon oscillator package enables the direct replacement of 32.768 kHz crystals of the 2012 series, as both 32.768 kHz solutions have the same layout dimensions.
With the unique and extremely low current consumption of <1.0µA, the SMD silicone 32.768 kHz oscillators impress with very tight frequency tolerances of ±5 ppm (overall) to ±10 ppm (initial) and thus significantly exceed the temperature stabilities of conventional quartz crystals and crystal oscillators with 32.768 kHz.
The standard housing dimensions are 1.5x0.8mm or 2.0x1.2mm, depending on the type. In contrast to conventional quartz crystals, the ULPO and ULPPO series allow several ICs (MCU, RTC, BLE, etc.) to be clocked simultaneously thanks to the LVCMOS-compatible output signal. In addition, external circuit capacitors are no longer used for these MICRO-SMD oscillators, which saves additional space on the circuit board compared to the quartz and also saves PCB costs due to the significantly lower space requirement. The total power consumption of a BLE solution with ULPO or ULPPO is a good 60% lower than when using a 32,768 kHz quartz crystal.

PETERMANN-TECHNIK offers a wide range of 32,768 kHz solutions for different requirements in electronics development. These include classic crystals, crystal oscillators, ultra low power silicon oscillators and RTCs. These products are suitable for standard industrial applications as well as for battery-powered devices such as BLE, IoT, wearables or smart metering. Developers can therefore choose between cost-optimized and high-performance clock solutions depending on the system requirements. The large selection of designs, performance data and possible applications makes it easier to integrate them into modern electronic designs.
The 32,768 kHz crystals from PETERMANN-TECHNIK are available with frequency tolerances at 25°C of ±10 to ±20 ppm. They are available in the standard temperature range from -40 to +85°C and thus reliably cover many industrial applications. This combination of tolerance and temperature range is particularly important when stable real-time clocking is required. Solutions for special requirements in the automotive sector are also available on request. These can be specified according to AECQ200 or AECQ100.
32,768 kHz silicon oscillators are particularly advantageous when low power consumption, high accuracy and compact designs are required. With a power consumption of less than 1.0 µA, they are ideal for battery-powered applications such as Bluetooth Low Energy, IoT or wearables. At the same time, they offer very tight frequency tolerances of ±5 ppm overall to ±10 ppm initial. This means they significantly exceed the temperature stability of conventional 32,768 kHz crystals and quartz oscillators. In addition, the LVCMOS-compatible output signal enables the simultaneous clocking of several ICs such as MCU, RTC or BLE devices.
MICRO-SMD 32.768 kHz oscillators are particularly worthwhile in compact designs with high demands on space requirements and system integration. Depending on the type, the standard housings are available in 1.5x0.8 mm or 2.0x1.2 mm and are therefore suitable for very small designs. The 2.0x1.2 mm housing also enables the direct replacement of 32.768 kHz crystals from the 2012 series, as identical layout dimensions can be used. In contrast to crystals, no external circuit capacitances are required, which saves additional space on the PCB. This simplifies the design and reduces PCB costs at the same time.
Ultra Low Power 32.768 kHz oscillators are particularly suitable for applications with strict requirements for energy efficiency and miniaturization. These include Bluetooth Low Energy, IoT devices, wearables, RTCs, mobile communication, smart metering, smart housing as well as consumer, medical and industrial applications. Thanks to their extremely low power consumption of less than 1.0 µA, they make a significant contribution to extending battery life. According to the page content, the total power consumption of a BLE solution with ULPO or ULPPO series is a good 60% lower than when using a 32,768 kHz crystal. At the same time, developers benefit from high frequency stability and a compact, integration-friendly design.
PETERMANN-TECHNIK is the right choice for 32,768 kHz solutions because the company offers a particularly extensive product range of crystals, crystal oscillators, ultra low power silicon oscillators and RTCs. Customers benefit from low cost, high performance solutions designed for both industrial applications and modern battery-powered devices. The portfolio specifically covers different requirements in terms of accuracy, power consumption, size and temperature behavior. The MICRO-SMD silicon oscillators in particular impress with their very low power consumption, high stability and simple integration without external circuit capacitance. Automotive solutions are also available on request, making PETERMANN-TECHNIK a strong and flexible partner choice for sophisticated frequency solutions.
