Overview

The ASEM1-50.000MHZ-LC-T is a high-performance CMOS output MEMS oscillator from Abracon designed to provide a stable 50.000MHz clock signal. Operating at 3.3V, this industrial-grade timing source utilizes MEMS technology to deliver superior reliability and shock resistance compared to traditional quartz crystals. It features a compact 3.2 x 2.5 mm QFN footprint, making it suitable for high-density PCB layouts.

Why Choose This Part

The MEMS-based architecture offers exceptional durability, maintaining a frequency tolerance of 50ppm across the full industrial temperature range of -40C to +85C. Unlike quartz oscillators, this device is immune to vibration-induced failures and features a significantly lower aging rate. Its low profile 0.85mm height is ideal for space-constrained mobile or wearable designs.

Applications

Industrial Networking
Provides a reliable reference clock for Ethernet controllers and industrial gateways requiring 50MHz timing.
Embedded System Main Clock
Acts as the primary external clock source for microcontrollers, FPGAs, and CPLDs in harsh environments.
Consumer Electronics
Suitable for portable media players and home appliances where small form factor and low power consumption are required.
Communication Infrastructure
Used in routers and switches to maintain signal integrity and timing synchronization across high-speed data paths.

Getting Started

To integrate this oscillator, connect the 3.3V supply to Pin 4 and GND to Pin 2, ensuring a 0.1uF decoupling capacitor is placed close to the VDD pin. The CMOS output on Pin 3 can directly drive most digital IC clock inputs; ensure PCB trace lengths are minimized to prevent signal reflection. For prototyping, this 4-pin QFN package requires a compatible land pattern or a dedicated SMT breakout board.
