STMicroelectronics Launches Low-Power Silicon Oscillators to Save Components and Simplify Design

Analog and mixed-signal IC market recently launched STMicroelectronics STCL1120 series silicon oscillators, quick start of new products, anti-vibration, anti-shock and strong electromagnetic interference (EMI) capacity, low current consumption, chip select control functions other than the power source Management The brand's silicon oscillator is easier and more energy efficient.

The first products of the STCL1120 series are 10MHz, 12MHz and 16MHz oscillators. 12MHz product start-up time of only 50 microseconds, the current work in similar products in the lowest (0.65mA), chip-select feature allows engineers to save energy, this product is low cost, high stability and durability, is an alternative to ceramic or crystal oscillator The best solution. Another great advantage of the STCL1120 is that it eliminates the need for external components and solves the capacitor matching problems that often occur with ceramic resonators. The STCL1120 is also powered directly from a 5V supply.

STCL1120 external chip select pin allows design engineers to easily stop the clock when the application is in standby mode, the oscillator current is reduced to 3 microamperes or less, save more energy. Compatible with CMOS push-pull output pin may generate a square wave signal, so that the oscillator components directly interface a circuit board, including a logic device, a microcontroller, the FPGA (field programmable gate array) and ASIC (application specific integrated circuit).

The accuracy of the fixed operating frequency of the STCL1120 is ±1.5% under all operating conditions. ST also introduced a 32kHz silicon oscillator and will soon introduce a derivative of this product. STCL1120 rated operating temperature range of? 20 ℃ to + 85 ℃, certain applications including motor control, household appliances, building control devices, a display driving circuit, the charger and advanced low-speed USB peripherals (such as a computer keyboard or mouse).

The STCL1120 series is available in a 5-pin SOT23 package and is available in volume quantities.
