GreenCLK 3 Crystal Replacement Products

GreenCLK 3 (GCLK 3) is a silicon-based 32.768 kHz crystal replacement technology. Using a single MHz reference (crystal, XO, or TCXO), GCLK 3 generates a cost-effective timing solution with a single 32.768 kHz clock output and a single MHz clock output.

Replacing 32.768 kHz RTC with GCLK 3 reduces component count, board space, and BOM cost.


Configuration Options:

  • Stability Over Temperature for 32.768 kHz Applications
    • ±15 PPM 32.768 kHz clock stability over -40C˚ to 85C˚ range
  • Ultra-Low Power Consumption
    • < 0.8 µA for 32.768 kHz in Hibernate Mode
