Overview

The SiT8008BI-12-33E-50.000000 is a high-performance 50 MHz MEMS oscillator from SiTime's popular SiT8008 series. It operates at 3.3V and provides a stable HCMOS/LVCMOS output across an industrial temperature range of -40 to 85 degrees Celsius. As a MEMS-based timing solution, it offers significantly higher reliability and shock resistance compared to traditional quartz crystal oscillators.

Why Choose This Part

This oscillator features +/-25ppm frequency stability and a programmable architecture that ensures high resilience to mechanical shock and vibration. Its MEMS construction eliminates the 'crystal aging' issues and start-up reliability concerns often found in quartz. The ultra-small 2025 package saves significant PCB real estate while maintaining standard 3.3V LVCMOS compatibility.

Applications

FPGA and MCU Clocking
Provides a stable 50 MHz reference clock for system controllers, FPGAs, and high-speed microcontrollers.
Industrial Networking
Suitable for Ethernet switches and industrial communication interfaces requiring stable timing in harsh environments.
Consumer Electronics
Ideal for high-definition video, streaming devices, and gaming consoles where a low-profile 2.0mm x 2.5mm footprint is required.

Getting Started

Integration is straightforward as it requires only a standard 0.1uF bypass capacitor between the VDD and GND pins. The Enable/Disable function on Pin 1 allows for power saving in battery-operated designs. Engineers can use standard PCB footprints for 2.0mm x 2.5mm oscillators, ensuring the trace length to the target IC is minimized to reduce EMI.
