Overview

The DSC1001BI1-066.6666T is a silicon MEMS-based CMOS oscillator providing a stable 66.6666 MHz clock signal. It is designed to replace traditional crystal oscillators, offering superior shock and vibration resistance in a standard 5.0mm x 3.2mm VDFN package. This part operates across a wide supply voltage range of 1.7V to 3.6V, making it compatible with various logic levels.

Why Choose This Part

This MEMS oscillator eliminates the risk of 'crystal fracture' and provides excellent frequency stability of +/-20 ppm across the extended industrial temperature range of -40C to +85C. It features a low-power standby mode and a wide supply voltage range, reducing the need for level shifting or multiple LDOs in mixed-voltage systems.

Applications

Industrial Automation Systems
Provides a robust timing source for PLCs and industrial controllers exposed to mechanical stress.
Embedded Computing
Acts as a reliable system clock for microprocessors and FPGAs requiring a 66.6666 MHz reference.
Consumer Electronics
Utilized in high-reliability consumer goods where a low-profile, battery-friendly oscillator is required.

Getting Started

To integrate this oscillator, ensure a 0.1uF bypass capacitor is placed as close as possible to the VDD pin. The output can drive standard CMOS loads directly, and the standby pin (Pin 1) should be pulled high for normal operation or low to reduce power consumption.
