Abracon | ATXK-H Miniature TCXO

32.768kHz TCXOs

Abracon’s 32.768kHz Miniature Temperature Controlled Crystal Oscillators (TCXOs) are designed for ultra-low frequency stability in applications like RTCs, IoT, and timing synchronization for networks. This device produces a CMOS waveform output and can be used under a 3.3 V, 2.5V, and 1.8V supply voltage. While it is optimized for low power consumption, the device’s available frequency tolerances are ±3.8ppm over -10 to +60°C, ±5.0ppm over -40 to +85°C, & ±8.0ppm over -40 to +105°C. The ATXK-H series is developed for precise timing in space constrained environments like wearables or portable electronics.
