Overview

The SG-210STF is a fixed-frequency 50 MHz crystal oscillator (XO) designed for high stability in a compact 2.50mm x 2.00mm package. It supports a wide supply voltage range from 1.8V to 3.3V and features a standby function that reduces power consumption by powering down the internal circuitry when not in use. With an extended operating temperature range up to 105 degrees Celsius, it is suitable for industrial and demanding environment applications.

Why Choose This Part

The SG-210STF offers a broad 1.8V to 3.3V operating range, eliminating the need for dedicated voltage regulators in multi-rail systems. Its +/-50ppm frequency stability and tiny 2520 footprint make it an efficient choice for dense PCB layouts requiring high reliability.

Applications

Microcontroller Clocking
Provides a stable 50 MHz reference clock for high-speed MCUs and FPGAs requiring a CMOS input.
Industrial Automation
Reliable timing source for PLC modules and industrial sensors operating in environments up to 105C.
Low-Power IoT
Utilizes the standby function to conserve battery life in wireless nodes that remain in sleep modes for extended periods.
Networking Equipment
Serves as a local oscillator for Ethernet controllers and communication interface logic.

Getting Started

When designing with this oscillator, place a 0.01uF to 0.1uF bypass capacitor as close as possible to the VCC pin to minimize noise. Ensure the Standby (ST) pin is driven high for normal operation or pulled low to enter power-down mode. Verify that the CMOS load capacitance at the output does not exceed the manufacturer specification to maintain signal integrity and rise/fall times.
