MicroClock devices facilitate manufacturers to decrease the size and maximize the battery life of sensor modules, smart wearables, sensor modules, and other miniature, battery-driven instruments.

FREMONT, CA: Integrated Device Technology (IDT), a Renesas Electronics Corporation company, announced the accessibility of its new MicroClock family of clock generators. The generators are optimized for pocket-sized, battery-powered devices, such as smartwatches, fitness monitors, hearables, portable medical devices, and equipment connected to the Internet of Things (IoT). The MicroClock tools are ideal for the products because of the factors like miniature size, programmability, and low power consumption.

IDT is recognized among CIO Review’s 20 Most Promising High-Performance Computing Technology Solutions Providers for the year 2015. Integrated Device Technology develops system-level solutions that enhance its customers’ applications. The enterprise specializes in memory and logic, clocks and timing, interface and connectivity, power management, sensor products, and RF products. “We have several leading solutions that contribute to a state-of-the-art high-performance computing ecosystem. Some have called it ‘supercomputing at the edge,’ because we’re putting our solutions at the edge of wireless networks,” asserts Sean Fan, Senior Vice President and Corporate General Manager, Computing & Communications Division at IDT. 

The small size of MicroClock ICs, 2 mm x 2 mm that has an aptitude to output up to three frequencies can decrease the board space desirable for timing devices by 80 percent. The desired size is achieved by eliminating the requirement of multiple crystal oscillators and providing a reliable clock source. Furthermore, the capability to output unique frequency serves as a critical benefit for small battery-powered devices, facilitating product designers to amplify the battery size or minimize the overall size of the creation.

Balancing the size gains is the ultra-low power consumption of the MicroClock series that consumes less than 1 μA of current. The low power consumption maximizes battery life for smart wearables and other consumer devices so that they can function longer between charges. Low power is also significant for IoT connected sensors used in industrial applications, smart city, and other tools that work where electricity is unavailable. 

The extraordinary programmability of the devices represents that the program aptitude can easily be configured to meet a particular requirement of every application, making it highly-flexible to speed up time-to-market. Chief examples include support for programmable VCO (Voltage-Controlled Oscillator) and PLL (Phase Locked Loop) source selection that facilitates users to advance power consumption. IDT’s MicroClock line of programmable clock generators at present comprises of four devices: the latest 5X1503 and 5L1503 along with 5X2503 and 5L2503.
