This is Si5351A I2C 8 Khz-160 Mhz Clock Generator Breakout Board Module.

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.

Applications:

1. HDTV, DVD/Blu-ray, set-top box
2. Audio/video equipment, gaming
3. Printers, scanners, projectors
4. Residential gateways
5. Networking/communication
6. Servers, storage
7. XO replacement

Features:

1. Generates up to 8 non-integer-related
2. Frequencies from 8 kHz to 160 MHz
3. I2C user-definable configuration
4. Exact frequency synthesis at each output (0 ppm error)
5. Highly linear VCXO
6. The optional clock input (CLKIN)
7. Low output period jitter: 100 ps pp
8. Configurable spread spectrum selectable at each output
9. Operates from a low-cost, fixed frequency crystal: 25 or 27 MHz
10. Supports static phase offset
11. Programmable rise/fall time control
12. Glitchless frequency changes

Package Includes:

1 x Si5351A I2C Clock Generator Breakout Board Module
