32.768 kHz and MHz
GreenCLK
General Description
The SLG3NB3331 uses a 25 MHz Reference Crystal to pro-
vide one 32.768 kHz clock output and three 25 MHz clock
outputs. The part supports a non-rechargeable coin cell bat-
tery (ex. CR2032) as the power source for the ultra low power
Hibernate mode operation.
Features
• 32.768 kHz GreenCLK technology for RTC
• Scalable VIO
• Improved performance over temperature
• Supports Industrial temperature range
• Smaller package and layout foot print
• 16-pin TQFN: 2 x 3 x 0.75 mm, 0.4 mm pitch
• Pb-Free / Halogen-Free / RoHS compliant
Output Summary
• 1x 32.768 kHz clock output (1.8 μA in Hibernate Mode)
• 3x 25 MHz clock outputs (2.5 mA in Active Mode)

Notes:
1. Type Definitions
• PWR: power
• GND: ground
• I: input
• O: output
• SE: single ended signal
2. It is recommended that all Power Supply pins have a decoupling capacitor attached (0.1 μF minimum).
3. When CR coin cell battery is used, place a 301 Ω resistor between the coin cell and the decoupling capacitor to meet the UL safety
requirement.
