Jopto 2PCS Si5351A I2C 25MHZ Clock Generator Breakout Board 8KHz to 160MHz Compatible with Arduino, CJMCU-5351 Si5351A Si5351 High Frequency Signal Square Wave Frequency Generator Signal Generator

• This Si5351A clock generator chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150+ MHz.
• Si5351 is an I2C configurable clock generator that can replace crystals, crystal oscillators, VCXOs, phase-locked loops (PLL) and fan-out buffers for cost-sensitive applications.
• Based on a PLL/VCXO + high resolution MultiSynth fractional divider architecture, the Si5351 can generate any frequency up to 160 MHz on each of its outputs with 0 ppm error.
• 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.
• Onboard 3.3V voltage regulator, electric frequency conversion circuit compatible with 3.3V and 5V TTL logic levels.
