32kHz output crystal oscillator IC 7202 series
Achieving low power consumption and miniaturization - Launch of the CMOS IC "7202 Series" for 32.768kHz output crystal oscillator modules.
The 7202 series is a CMOS IC for crystal oscillator modules that incorporates an oscillation circuit for AT-cut quartz crystal oscillators at 16.777216MHz (or 25.165824MHz, 33.554432MHz) and outputs 32.768kHz with a division ratio of 512 (or 768, 1024). It is designed to operate at 125°C. By using an AT-cut crystal, it enables the realization of a 32.768kHz output crystal oscillator with superior frequency temperature characteristics and a shorter oscillation startup time compared to products using tuning fork oscillators. Compared to the conventional model (5059), it reduces power consumption by 90%, shrinks the chip size by 40%, and supports a wide operating supply voltage range (1.6 to 3.63V) and an operating temperature range (-40 to 125°C).
