Si5351 Clock Generator Module 8KHz-160MHz I2C for Arduino 3-5VDC
Price in Sri Lanka

This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz>

Features:

• The Si5351A clock generator is an I2C controller clock generator
• It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions
• By setting up the PLL and dividers you can create precise and arbitrary frequencies
• There are three independent outputs, and each one can have a different frequency
• Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional SMA connector
