Overview

The DSC1001DL2-050.0000T is a 50 MHz silicon MEMS oscillator that provides a high-stability CMOS output. It is designed to replace traditional crystal oscillators, offering better reliability and resistance to mechanical shock and vibration in a compact 2.50mm x 2.00mm VDFN package. This part operates across a wide supply voltage range from 1.7V to 3.6V and features a standby mode for power conservation.

Why Choose This Part

The MEMS-based architecture eliminates the need for external capacitors and provides superior frequency stability of +/-25ppm over an extended temperature range of -40C to +105C. Its low-power design and small VDFN footprint make it ideal for space-constrained mobile and industrial applications.

Applications

Microcontroller Clocking
Provides a precise 50 MHz reference clock for high-speed MCUs and digital signal processors.
Industrial Automation
Reliable timing in harsh environments where mechanical vibration would degrade traditional quartz crystals.
Battery-Powered Devices
Utilizes the standby (power down) function to minimize current draw when the system is inactive.

Getting Started

To use this oscillator, connect the 50 MHz CMOS output directly to the target IC's clock input and ensure the standby pin is tied high for normal operation. Decouple the supply voltage (1.7V to 3.6V) with a 0.1uF ceramic capacitor placed as close to the VDD pin as possible.
