Overview

The SIT8008AI-12-33E-8.000000 is a high-performance 8 MHz MEMS oscillator from SiTime's SiT8008 series. It operates at a 3.3V supply voltage and provides a robust HCMOS/LVCMOS output with an enable/disable function for power management. Built on silicon MEMS technology, this oscillator offers superior reliability and resistance to shock and vibration compared to traditional quartz crystals.

Why Choose This Part

This MEMS-based oscillator provides a frequency stability of +/-25ppm, ensuring high precision over its entire operating temperature range. Its 2.50mm x 2.00mm 4-SMD package is footprint-compatible with standard quartz oscillators while offering 30 times higher reliability and much better immunity to EMI.

Applications

Microcontroller Clocking
Provides a stable 8 MHz reference clock for MCUs and SoCs in industrial and consumer electronics.
Industrial Automation
Utilized in factory equipment where mechanical robustness is required across an operating temperature range of -40C to 85C.
Low-Power Systems
The enable/disable function allows for power savings in battery-operated devices by shutting down the output when not in use.

Getting Started

To use this oscillator, provide a stable 3.3V supply to the VDD pin and place a 0.1uF decoupling capacitor close to the device. Ensure the output load capacitance does not exceed the HCMOS specification to maintain signal integrity and rise/fall times. The OE (Output Enable) pin should be pulled high for normal operation or low to enter standby mode.
