Overview

The ASDMB-50.000MHZ-LC-T is a 50 MHz MEMS-based oscillator designed for high reliability and low power consumption in a compact 2.50mm x 2.00mm package. It features LVCMOS output logic and supports a wide supply voltage range from 1.8V to 3.3V, making it compatible with various digital logic levels. A standby function allows the device to power down, significantly reducing current draw in battery-operated systems.

Why Choose This Part

The use of a MEMS resonator ensures superior shock and vibration resistance compared to traditional quartz crystal oscillators. Its compact 4-SMD footprint saves board space, while the +/-50ppm frequency stability provides reliable timing across the full operating temperature range.

Applications

Microcontroller Clocking
Provides a stable 50 MHz reference clock for high-speed MCUs and DSPs requiring low-jitter performance.
Portable Electronics
Utilizes the standby (power down) function to extend battery life in handheld devices.
Network Equipment
Serves as a reliable timing source for Ethernet and communication interfaces requiring standard CMOS levels.
Industrial Automation
Operates reliably in harsh environments with an extended temperature range of -40C to +85C.

Getting Started

To use this oscillator, provide a stable DC supply between 1.8V and 3.3V with a 0.1uF decoupling capacitor placed close to the VDD pin. Connect Pin 1 to a logic high level for normal operation or a logic low level to enter standby mode. Ensure the LVCMOS output trace is short and properly terminated to minimize signal reflections at 50 MHz.
