GreenCLK 3 Crystal Replacement Products
Crystal Replacement Products
A team of engineers is ready to answer your questions
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.
