Microchip’s MEMS clock generator with wide frequency range, reduces board space by 80 percent by replacing up to three crystals/oscillators
Demand for compact and portable IoT electronics devices is accelerating, and product designers need a solution that has less application size and extended battery life. The timing devices are the main operating components in IoT devices, but they need multiple components to meet frequency requirements which increases the board space and power consumption. To resolve these design challenges, Microchip Technology has launched small MEMS clock generator.
Reduces Space Consumption
Nowadays, system designers place multiple crystals/oscillators or use clock generator with an external crystal for reference input on a board, to meet the range of frequencies needed in smart devices. But this new MEMS clock generator of DSC613 family can reduce space by 80 percent by replacing up to three crystals and oscillators on a board.
The DSC613 family 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 two PLLs with AnyRate clock synthesisers, enables the device to generate any frequency between 2 kHz and 100 Mhz and also supports up to three clock outputs. So, at approximately five milliamps (mA) power consumption with three outputs running, the family provides up to 45 percent power savings when compared to a solution that uses three low-power quartz oscillators. For additional power savings, the clock output can be turned off through the output enable pin. And this feature makes this device ideal for microcontroller-based embedded systems

The DSC613 family supports compact devices that require low-power operation because of their compact package size and extensive frequency flexibility. Some of its applications are:
- Digital cameras
- Smart speakers
- Virtual Reality (VR) headsets
- Streaming sticks
- Set-top boxes
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.
The DSC613 family is supported by Microchip’s ClockWorks online configurator tool.
Clock configuration includes output frequency, control pin function, package size, PPM accuracy and temperature range. Up to three output drive strengths are available based on the custom board loading condition. Spread-spectrum clocks are also available for EMI reduction. Application support, including board layout guidelines and schematics review, is also available.
The DSC613 family is available now for sampling and in volume production.
