SiTime Corporation 1 Hz to 462.5 kHz Oscillators SiT1534AC-H5-DCC-00.032

The SiT1534 is an ultra-small, ultra-low power programmable oscillator capable of generating frequencies from 1 Hz to 32.768 kHz, designed for battery-powered applications such as mobile phones, fitness watches, and RTC reference clocks. It is available in a 1.5 x 0.8 mm chip-scale package (CSP) and is pin-compatible with 2.0 x 1.2 mm XTAL SMD packages. The device operates from a 1.5 V to 3.63 V supply across temperatures from -55°C to +85°C, with typical current consumption below 1 µA and no external load or bypass capacitors required. It features programmable output swing via NanoDrive™ technology, meets RoHS and REACH standards, and offers a PFAS-free option. Frequency tolerance is within 20 ppm at 25°C and up to 150 ppm over the full temperature range.
