توضیحات: این محصول ماژول راه اندازی آی سی Si5351 است. این آی سی یک مولد سیگنال کلاک یا Clock Generator سه کاناله است که با استفاده از رابط I2C کنترل و راه اندازی می شود. این آی سی جایگزی مناسبی برای کریستال ها، کریستال اسیلاتورها، VCXOها و PLL ها و Fanout بافرها است. این آی سی می تواند سیگنال خروجی از فرکانس 8 کیلوهرتز تا 160 مگاهرتز ایجاد کند.
CJMCU-5351 Si5351A Si5351 I2C Clock Generator Breakout Board Module Signal Generator Clock 8KHz-160MHz For Arduino DC 3V
Description: Never hunt around for another crystal again, with the Si5351A clock generator breakout ! This 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. 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. We put this handy little chip onto it's own breakout board PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC. We also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic.
