Overview

The SG-210STF 50.0000MS5 is a fixed-frequency 50 MHz CMOS crystal oscillator designed for stable clock generation in space-constrained designs. It operates across a wide supply voltage range of 1.8V to 3.3V, making it compatible with various logic levels without needing a dedicated regulator. The device includes a standby function that reduces power consumption by powering down the internal oscillation circuit when not in use.

Why Choose This Part

This oscillator features a compact 2.5mm x 2.0mm SMD footprint and a low profile of 0.8mm, ideal for high-density PCB layouts. It offers a frequency stability of +/-25ppm and maintains operation across an industrial temperature range of -40 C to +85 C.

Applications

Microcontroller Clock Source
Provides a reliable external 50 MHz reference for high-speed MCUs and FPGAs requiring tighter stability than internal RC oscillators.
Communication Interfaces
Acts as a precision frequency source for Ethernet controllers, USB peripherals, and industrial bus timing.
Battery-Powered Electronics
Utilizes the standby (power down) function to extend battery life in portable instrumentation and IoT edge devices.

Getting Started

To use this oscillator, connect Pin 1 (ST) to VCC or leave it open for normal operation, and pull it to GND to enter standby mode. Ensure a 0.01uF to 0.1uF bypass capacitor is placed as close as possible to the VCC pin to minimize power supply noise.
