Overview

The DSC1123DI2-100.0000T is a high-performance MEMS-based 100 MHz LVDS oscillator designed for precision clocking. It provides a stable differential output with +/-25ppm frequency stability across a wide supply voltage range of 2.25V to 3.63V. Utilizing Microchip MEMS technology, this device eliminates the need for a quartz crystal, offering superior reliability and mechanical shock resistance.

Why Choose This Part

The MEMS resonator technology provides excellent immunity to vibration and mechanical shock compared to traditional quartz crystals. Its differential LVDS output ensures high-speed signal integrity and low electromagnetic interference (EMI) in dense PCB layouts. Additionally, the wide operating temperature range of -40C to +85C makes it suitable for industrial-grade deployments.

Applications

Getting Started

To integrate this oscillator, ensure a 0.1uF decoupling capacitor is placed close to the VDD pin and follow standard LVDS termination practices, typically a 100-ohm resistor across the differential pair. The Enable/Disable pin allows for power savings by shutting down the output when not required. No external tuning or load capacitors are needed for the MEMS resonator.
