Overview

The DSC1001BI2-024.0000T is a 24 MHz MEMS-based CMOS oscillator designed for low-power operation and high reliability. It offers excellent frequency stability of +/-25ppm across an extended industrial temperature range of -40C to +85C. This component is an all-silicon alternative to traditional crystal oscillators, providing better immunity to mechanical shock and vibration.

Why Choose This Part

The MEMS-based architecture eliminates the need for external crystals or load capacitors, simplifying PCB routing and reducing BOM count. It supports a wide supply voltage range from 1.7V to 3.6V, making it compatible with modern low-voltage digital logic. Additionally, the integrated standby mode significantly reduces power consumption when the system clock is not required.

Applications

Microcontroller Clocking
Providing a stable 24 MHz reference clock for MCUs and SoCs in industrial and consumer electronics.
Battery-Powered Devices
Utilizing the low power consumption and standby function to extend battery life in portable hardware.
Industrial Automation
Reliable timing in high-vibration environments where traditional quartz crystals may fail.
USB Peripherals
Serving as the base frequency source for high-speed communication interfaces requiring 24 MHz timing.

Getting Started

To integrate this oscillator, connect the 24 MHz output directly to the XTAL1/CLKIN pin of your processor and ensure a 0.1uF decoupling capacitor is placed close to the VDD pin. If using the standby function, pull pin 1 low to enter power-down mode; pull it high for normal operation. Ensure the VDFN land pattern matches the 5.0mm x 3.2mm footprint specifications found in the Microchip datasheet.
