Foreword:Microchip Technologies recently released the DSC613, a 3-output low power MEMS clock generator housed in a tiny package that produces up to three separate frequency outputs at electronica 2018.

Wearable devices and Internet of Things (IoT) are two of the most important areas of development in electronics today, and the two criteria they share are the need to conserve both power and board real-estate.The 3-Output Low Power MEMS Clock Generator_DSC613 meet this need that save board space highly.

Who is DSC613

The DSC613 is a micro-electronic-mechanical system (MEMS) oscillator complete within a package as small as 1.6mm x 1.2mm that eliminates the need for three separate quartz oscillator crystals and their associated components. The three available frequency outputs cover a range of possibilities from 2 kHz to 100 MHz.

The DSC613 family of devices is industry’s smallest MEMS clock generator that can replace up to three crystals and oscillators on a board, reducing timing component board space by up to 80 percent. The clock generator eliminates the need for an external crystal by integrating the low power and high stability Micro-Electro-Mechanical Systems (MEMS) resonator. The family includes two low power fractional PLLs that provide leading frequency flexibility and robust jitter performance. Customer can configure 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. 

The DSC613 is a highly configurable device and is factory programmed to meet the customer’s needs. Please go to ClockWorks Configurator  to configure the output frequencies and control functions,  generate custom part number and data sheet, and order samples.

What Is MEMS

MEMS is an acronym for micro electro mechanical system. They are 3D microstructures and, most importantly, they can be fabricated using the same techniques used to build semiconductors. For oscillators, what is built is, essentially, a tiny tuning fork that, like its full-sized cousin, vibrates at a known, predetermined frequency.

What is the core of DSC613

The core of the DSC613 is a MEMS resonator and two-phase lock loops (PLLs).This innovation can reduce the board space required for timing circuitry by approximately 80%, with a corresponding reduction in overall system weight. Due to the miniscule current requirements of the MEMS resonator and the two PLLs, power requirements are a scant 1 µA standby in standby current, and an economical 5.2 mA in active mode.

Related benefit of DSC613

The DSC613 allows customers to adjust the output frequency and control pin function has a wide operational voltage range of 1.71V to 3.63V, and up to 100MHz operation.

Aside from the three output frequencies, among the options that can be chosen are the temperature range, which can be as wide as  -40°C to 125°C, the package size, what the control input of pin 1 will affect, and even frequency stability, which can be as tight as +/-20ppm.
