SiT8021AI-J4-XXS-2.048E
Overview
The SiT8021AI is an ultra-small, low-power MEMS oscillator operating at 2.048 MHz. Part of the SiTime muPower series, it is specifically designed to replace traditional quartz crystals in space-constrained, battery-powered electronics. It features a tiny 1.5mm x 0.8mm package and consumes significantly less power than standard oscillators.
Why Choose This Part
This MEMS oscillator offers 100 ppm frequency stability across an industrial temperature range of -40 to +85 degrees Celsius. Its 1.5mm x 0.8mm footprint is substantially smaller than typical quartz solutions, and its MEMS construction provides superior resistance to mechanical shock and vibration.
Applications
Getting Started
When integrating this oscillator, ensure the 1.8V supply rail is stable and place a 0.1uF bypass capacitor as close to the VDD pin as possible. Since this is a factory-programmed MEMS device, no external loading capacitors are required, simplifying the PCB layout compared to crystal resonators.
