Driving wearables and IoT with small quartz frequency devices

18 August 2015

AEL Crystals is playing a role in reducing the size of the core technology for wearable and IoT devices, with its three latest products. 

The 1610 Watch Crystal is a small 32.768kHz watch crystal, measuring just 1.6 x 1.0 x 0.5mm (max). It is available with wide operating temperature ranges up to -40 to +105°C and is robust and reliable in operation, initial stabilities can be specified between +/-10 and +/-50ppm , making it suitable for wireless modules, in-car devices, Bluetooth devices and mobile phones, as well as wearable devices, such as smart watches, fitness trackers, medical and activity monitoring devices.

For reliable operation, the ESR (Equivalent Series Resistance) is 60kO (Max), making the 1610 Watch Crystal particularly suitable for low ESR applications such as Bluetooth Low Energy chipsets. Furthermore, AEC-Q200 compliant versions are available, making it ideal for use in the automotive industry.

The 1210 Crystal measures just 1.2 x 1.0 x 0.33mm (max). It can be supplied between 36.0 and 80.0MHz. Operating temperature can be specified up to -40 to +125°C, with temperature stability from +/-10 to +/-50ppm and initial stability as low as +/-7ppm. AEC-Q200 compliant versions are also available. 

AEL Crystal’s smallest oscillator is the 1612. It measures just 1.6 x 1.2 x 0.7mm (max) and operates across a temperature range from -40 to +85°C. It is reliable, with a temperature stability of +/-10 to +/-50ppm, and initial stability of +/-7 to +/-50ppm. Additionally, it has a wide operating frequency range of 1.0 to 80.0MHz and operates from a 1.8, 2.5 or 3.3V supply.
