Overview

The SIT1602BI-12-33E-50.000000 is a high-performance 50 MHz MEMS oscillator from SiTime's SiT1602 series. It provides a stable LVCMOS/HCMOS output with +/-25ppm frequency stability across an industrial temperature range of -40C to 85C. This component is designed for high-reliability applications where traditional quartz crystals may be prone to mechanical failure.

Why Choose This Part

This oscillator features MEMS technology which offers 20 times better reliability and much higher resistance to shock and vibration compared to quartz. With a low maximum supply current of 4.5mA at 3.3V, it is efficient for power-sensitive designs while maintaining a tight +/-25ppm stability.

Applications

System Clock Generation
Provides a precise 50 MHz reference clock for microcontrollers, FPGAs, and digital signal processors in industrial automation.
Ethernet and Networking
Acts as a stable frequency source for networking equipment requiring 50 MHz for PHY or MAC timing.
Embedded Systems
Suitable for high-vibration environments such as robotics or heavy machinery where MEMS technology offers superior durability over quartz.

Getting Started

Integration is straightforward as it requires a standard 3.3V supply and utilizes a common 3225-sized 4-pin SMD footprint. Ensure a 0.1uF bypass capacitor is placed as close as possible to the VDD pin to minimize power supply noise. The Enable/Disable pin (Pin 1) allows for power savings by shutting down the output when not in use.
