Key Facts:
  • Flexible solution covers a wide frequency range without the need for an external crystal
  • Single-chip 1.6 mm x 1.2 mm solution integrates a MEMS resonator and two low-power PLLs
  • Up to 45 percent power savings compared to a three low-power quartz oscillators solution
  • Reduces design size whilst extending battery life for IoT and portable designs



Microchip announces the industry’s smallest MEMS clock generator. The DSC613 can replace up to three crystals and oscillators on a board, reducing timing component board-space by up to 80 percent. The device eliminates the need for an external crystal by integrating a low-power and high-stability Micro-Electro-Mechanical Systems (MEMS) resonator.
 
Timing devices are central to the operation of compact Internet of Things (IoT) and portable electronics, but clock sources traditionally require multiple components to meet the frequency requirements of consumer devices, thus consuming board space and power. The DSC613 clock family allows product designers to reduce application size while extending battery life.
 
To support the range of frequencies required in today’s smart devices, system designers need to either place multiple crystals/oscillators next to the controllers on a board or use a clock generator with an external crystal for the reference input. The DSC613 family is a true 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 compact package size and extensive frequency flexibility makes the DSC613 family well suited for compact devices that require low-power operation, such as digital cameras, smart speakers, Virtual Reality (VR) headsets, streaming sticks and set-top boxes.
