Abracon ATXK-H14 32.768kHz Miniature Temperature-Controlled Crystal Oscillators (TCXOs) feature a typical frequency of 32.768kHz in a 2.15mm x 1.35mm x 1.1mm package. The Abracon ATXK-H14 TCXOs offer frequency stability options of ±3.8ppm over -10°C to +60°C, ±5.0ppm over -40°C to +85°C, and ±8.0ppm over -40°C to +105°C. These TCXOs provide 3.3V, 2.5V, and 1.8V supply voltage options and are ideal for use as a frequency reference for real-time clocks (RTCs) and for use in portable/wearable electronics and Internet of Things (IoT) applications.
