Overview

The DSC1001BI1-012.0000T is a 12 MHz silicon MEMS based oscillator designed to replace traditional quartz crystal resonators. It provides a CMOS output and supports a wide supply voltage range from 1.7V to 3.6V, making it suitable for low-power embedded designs. By utilizing MEMS technology, this device offers high reliability and resistance to mechanical shock and vibration.

Why Choose This Part

This MEMS oscillator provides superior frequency stability of +/-20 ppm and eliminates the need for external load capacitors required by quartz crystals. Its small 5.0mm x 3.2mm VDFN footprint and 0.85mm height enable high-density PCB layouts. The inclusion of a standby mode allows the device to consume minimal power when the system is inactive.

Applications

Microcontroller Clocking
Providing a stable 12 MHz reference clock for MCUs and SoCs in industrial and consumer electronics.
Portable Electronics
Leveraging the low-power standby function to extend battery life in handheld devices.
Industrial Automation
Utilizing the extended industrial temperature range of -40C to +85C for reliable operation in harsh environments.

Getting Started

To integrate this oscillator, connect the VDD pin to a decoupled 1.8V to 3.3V supply and the STDBY pin to a GPIO for power management. Ensure the output trace to the MCU clock input is kept short to minimize EMI and signal degradation. No external resonators or tuning capacitors are required, simplifying the hardware design phase.
