32.768 kHz oscillator quartz replacement technology

November 19, 2013 // By Graham Prophet
Silego Technology has introduced its third generation GreenCLK3TM 32.768 kHz oscillator family. At 1x1.6 mm the oscillators are the smallest availabled in standard plastic packaging. The product family is also available in die form with a total area of less than

The GCLK3 generation is 50% lower power, 50% improved in ppm accuracy, and greater than a 10 dB improvement in phase noise as compared previous generations. In the lowest power mode with only the 32.768 kHz clock output active, this new generation IC consumes just 0.75 µA (typical) at tighter ppm accuracy over temperature as compared to tuning fork quartz crystals. In full active mode with both MHz clock and 32.768 kHz outputs active the IC consumes around 0.9 ma with a MHz phase noise of less than -135 dBc/Hz at 1 kHz offset. Virtually all wireless standards may now be clocked with GCLK3 technology based products. Use them in mobile devices that require both MHz and 32.768 kHz crystals, and GPS systems with tighter ppm requirements over temperature. GCLK3 is compatible with Silego’s proprietary 0.27 mm Lo-Z ultra-thin packaging technology.
