STMicroelectronics's Latest Silicon Oscillators Rated at 16MHz

(Product News, 27 Jun 2008)

STMicroelectronics has released its STCL1120 family of silicon oscillators that features ratings of 10MHz, 12MHz and 16MHz, a short startup time of 50µs and 0.65mA operating current for the 12MHz version. A cost-effective and robust alternative to ceramic or quartz-based oscillators, the new releases require no external components, allowing designers to eliminate the capacitance matching typically necessary with ceramic resonators. The STCL1120 oscillators also operate directly from a 5V supply.

By implementing an external chip-select pin, the STCL1120 provides an easy way for engineers to stop the clock when the application is in standby mode, gaining extra power savings by reducing the oscillator current to less than 3 microamps. The push-pull, CMOS-compatible output produces a square wave for direct interfacing with on-board components including logic devices, microcontrollers, FPGAs and ASICs.

The devices have a fixed operating frequency accurate to within ±1.5 percent throughout all operating conditions. Specified for operation from -20°C to 85°C, the STCL1120 serves motor-control applications, home appliances, building controllers, display drivers, advanced battery chargers, and low-speed USB peripherals such as computer keyboards or mice.
