The XO2016BM-ULP-32.768KHz from Dynamic Engineers is an Ultra-Low Power Crystal Oscillator that operates at 32.768 kHz. It provides a CMOS output waveform (45-55% duty cycle) with a frequency stability of ±10 ppm. This crystal oscillator has a start-up time of less than 8 ms and a rise/fall time of 10 ns. It requires a DC supply of 1.5/1.8 V and consumes less than 1.8 µA of current. The oscillator is available in a package that measures 2.05 x 1.65 x 0.75 mm and is ideal for RTC reference clocks, wearable devices, sports video cams, ultra-small notebook PC, health and wellness monitors, and mobile phone applications.
