Overview

The SIT8008BI-23-33E-100.000000 is a high-performance 100 MHz MEMS oscillator from SiTime's SiT8008 series. It operates at 3.3V and offers a standard CMOS output with an integrated enable/disable function for power management. Built on a silicon MEMS resonator platform, this oscillator provides high reliability and resistance to shock and vibration compared to traditional quartz crystals.

Why Choose This Part

This MEMS oscillator features excellent frequency stability of +/-50ppm and high reliability with a wide operating temperature range up to 85C. The silicon-based architecture eliminates the risk of 'crystal burnout' and is significantly more resilient to mechanical stress and EMI than quartz equivalents. Its 3.3V supply and low power consumption make it suitable for energy-sensitive embedded designs.

Applications

Ethernet and Network Switches
Provides a stable 100 MHz reference clock for high-speed networking interfaces and PHYs.
FPGA and Processor Clocking
Serves as a reliable master clock for high-performance FPGAs, DSPs, and microcontrollers requiring 100 MHz.
Industrial Automation
Functions reliably in harsh industrial environments with an operating temperature range of -40 to 85 degrees Celsius.
Consumer Electronics
Used in digital cameras and video equipment where a compact 3.20mm x 2.50mm footprint is required.

Getting Started

Ensure proper decoupling with a 0.1uF ceramic capacitor placed as close as possible to the VDD pin. The enable/disable pin (Pin 1) can be driven by a GPIO to reduce system power consumption when the clock is not required. Since this is a complete oscillator module, no external load capacitors or quartz crystal tuning is necessary.
