MEMS clock generator MICROCHIP DSC612PI3A-010J with spread spectrum enable and frequency select pins
Product Overview
The DSC612 is a MEMS-based, crystal-less clock generator family offering ultra-small footprint and low power consumption. It generates up to two independent LVCMOS output clocks from 2 kHz to 100 MHz, eliminating the need for external crystals. Utilizing Microchips PureSilicon MEMS technology, it provides low jitter and high frequency stability across a wide range of supply voltages and temperatures. The device features configurable control pins for output enable/disable, standby, sleep, spread spectrum enable, and frequency select, enhancing reliability and accelerating product development. Available in compact VFLGA packages, it is suitable for low power, portable, consumer, and industrial applications.
