Overview

The ASEMB-25.000MHZ-XY-T is a 25 MHz MEMS-based oscillator designed for high reliability and precision in a compact 3.20mm x 2.50mm footprint. It supports a wide supply voltage range from 1.8V to 3.3V and offers an industrial-grade operating temperature range of -40C to 105C. This CMOS output oscillator features a standby power-down function, making it suitable for battery-powered applications requiring low current consumption when inactive.

Why Choose This Part

This oscillator features exceptional +/-10ppm frequency stability, ensuring high timing accuracy over its entire operating life. Its MEMS-based architecture provides superior shock and vibration resistance compared to traditional quartz crystals, while the wide 1.8V to 3.3V voltage range simplifies power rail integration.

Applications

Ethernet Controllers
Provides the standard 25 MHz reference clock required for many 10/100 Mbps Ethernet PHYs and MACs.
Industrial Control Systems
Used as a stable timing source for PLCs and industrial sensors operating in high-temperature environments up to 105C.
Portable Electronics
Utilizes the standby (power down) function to extend battery life in mobile handheld devices.
Microcontroller Clocking
Serves as an external high-speed clock source for MCUs requiring better frequency stability than internal RC oscillators.

Getting Started

To use this oscillator, connect Pin 4 to your supply voltage (1.8V to 3.3V) and Pin 2 to ground, placing a 0.1uF bypass capacitor as close to the VDD pin as possible. Pin 1 serves as the Standby control; pulling it low will disable the CMOS output on Pin 3 to save power. Ensure your PCB traces are short to minimize EMI and signal integrity issues at the 25 MHz operating frequency.
