Overview

The ASEMB-12.000MHZ-XY-T is a high-performance 12 MHz MEMS-based CMOS oscillator designed for reliable clock generation in compact electronic systems. It supports a wide supply voltage range from 1.8V to 3.3V and is housed in a miniature 3.2 x 2.5 mm QFN package. This oscillator is particularly notable for its high frequency stability of +/-10ppm across an extended temperature range of -40C to +105C.

Why Choose This Part

The MEMS-based architecture offers superior shock and vibration resistance compared to traditional quartz crystal oscillators. Its extremely tight frequency stability of +/-10ppm and wide operating temperature range make it suitable for high-reliability applications where timing precision is critical.

Applications

Industrial Control Systems
Provides a stable timing reference for PLCs and industrial sensors operating in harsh environments up to 105C.
Battery-Powered Handhelds
Utilizes the Standby (Power Down) function to minimize current draw and extend battery life when the system clock is inactive.
Precision Instrumentation
Leverages the +/-10ppm frequency stability for high-accuracy measurement and data acquisition hardware.
Embedded Computing
Serves as a reliable external clock source for microcontrollers and SoCs requiring a standard 12 MHz reference.

Getting Started

To use this oscillator, provide a decoupled supply voltage between 1.8V and 3.3V to Pin 4 and connect the output (Pin 3) to your target IC's clock input. Ensure the standby pin (Pin 1) is pulled high for normal operation or low to enter power-down mode. A 0.1uF bypass capacitor is recommended between the VDD and GND pins as close to the device as possible.
