Product Overview

The DSC612 is a MEMS-based, crystal-less clock generator family offering an ultra-small footprint and low power consumption. It generates up to two independent LVCMOS output clocks with frequencies ranging from 2 kHz to 100 MHz. Utilizing Microchip's PureSilicon MEMS technology, it provides low jitter and high stability, eliminating the need for external crystals and enhancing reliability. The device features configurable control pins for output enable/disable, standby, sleep, spread spectrum, and frequency selection, making it ideal for a wide range of low power, portable, consumer, and industrial applications.
