## Description

Si5351A I2C 25MHZ I2C High Frequency Signal Generator Breakout Board Square Wave Frequency Generator Signal Generator 8KHz to 160MHz 3-5VDC

## Features

- This chip has a precision 25MHz crystal reference and internal PLL and dividers.
- It can generate just about any frequency, from <8KHz up to 150+ MHz.
- The Si5351 is an I2C configurable clock generator that is ideally suited for replacing crystals, crystal oscillators, VCXOs, phase-locked loops (PLLs), and fanout buffers in cost-sensitive applications.
- It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions.
- Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional SMA connector.
