Euroquartz has launched a new range of miniature surface mount temperature-compensated crystal oscillators (TCXO), which benefit from very low current consumption in real-time clock applications.

The EME32T series offers frequency of 32.768kHz for real-time clock applications in a 3.28mm x 2.5mm x 1.3mm miniature SMD 4-pad package with a selection of supply voltage encompassing 1.8, 2.5, 3.0, 3.3 and 5.0V options. Current consumption of as little as 0.79µA at 1.8V is a major advantage in battery-controlled applications, while frequency stability is just ±5ppm over temperature range from -40 to 85°C.

Frequency stability versus voltage change is 0.2ppm for a 5% input voltage change, while frequency stability against ageing is 3.0ppm maximum for the first year.

Additional specifications include initial calibration tolerance of 1.5ppm at 25°C 2%, timing error over time of 2.628m/year, CMOS output logic with load of 15pF, 100ns maximum rise and fall time and duty cycle of 50% 10%. Start-up time is 1s maximum at 25°C (3s maximum over operating temperature range).

Euroquartz is an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters, and frequency-related products to the electronics manufacturing industry worldwide.

The company is AS9100 registered and designs and manufactures a comprehensive range of frequency control components for a wide range of customers including major OEMs covering a broad spectrum of applications including military and aerospace, communications, general electronics, computing, control systems, and petrochemical among many others.
