November 6, 2018 — Microchip Technology announced a MEMS clock generator. This device can replace up to three crystals and oscillators on a board. The DSC613 clock family is designed to eliminate the need for an external crystal by integrating a low-power Micro-Electro-Mechanical Systems (MEMS) resonator.
The DSC613 family is a single-chip solution that integrates a MEMS resonator and two low-power Phase-Locked Loops (PLLs) into a 6-pin DFN package as small as 1.6 mm x 1.2 mm. The package size and frequency flexibility makes the DSC613 family well suited for devices that require low-power operation, such as digital cameras, smart speakers, Virtual Reality (VR) headsets, streaming sticks and set-top boxes.
The DSC613 family supports up to three clock outputs from 2 kilohertz (kHz) to 100 megahertz (MHz), for microcontroller-based embedded systems. In an IoT application, for example, the clock generator can be used to provide a MHz main reference clock and 32.768 kHz Real-Time Clock (RTC) for the microcontroller (MCU), as well as another MHz clock for functions such as connectivity and sensors. The DSC613 family includes two low-power fractional PLLs with AnyRate clock synthesizers, which enable the device to generate any frequency between 2 kHz and 100 MHz.
MEMS products are built entirely with standard semiconductor processes, providing the same reliability and stability as integrated circuits, and the devices support up to -40 to +125 degrees Celsius temperature range with a stability of ± 20ppm.
