Overview

The DSC1001DL2-012.0000T is a 12 MHz silicon MEMS-based CMOS oscillator designed to replace traditional quartz crystals. This component provides a stable clock source in a compact 2.50mm x 2.00mm VDFN package and operates over a wide supply range from 1.7V to 3.6V. Its MEMS architecture offers enhanced reliability and resistance to mechanical shock and vibration compared to quartz resonators.

Why Choose This Part

The MEMS-based design eliminates the need for external load capacitors and is significantly more robust against mechanical stress than quartz. It features a very low standby current of 15uA and a fast startup time of 1.3ms, making it ideal for duty-cycled battery applications. With a stability of +/-25ppm and high ESD protection (4kV HBM), it ensures consistent performance in demanding electrical environments.

Applications

Microcontroller Clocking
Provides a stable 12 MHz reference clock for general-purpose MCUs in industrial and consumer applications.
USB Peripheral Timing
Suitable for USB-based systems requiring a 12 MHz base frequency for internal PLL synchronization.
Low-Power Handhelds
Utilizes the standby function (15uA max current) to extend battery life in portable electronics.
Industrial Sensors
Operates reliably in harsh environments with an extended industrial temperature range of -40C to 105C.

Getting Started

To implement this oscillator, connect VDD to a stable 1.8V to 3.3V supply with a 0.1uF bypass capacitor and ground the VSS pin. The output can drive CMOS loads up to 25pF, and the standby pin should be pulled high for active operation or low to enter power-down mode. No external tuning or matching components are required for the MEMS resonator.
