With a precision 25 MHz crystal reference and internal PLLs and dividers, it eliminates the need to hunt for specific crystals or oscillators for your projects.\n\nThe breakout provides three independent outputs, each configurable to a different frequency with 3 Vpp output levels. Outputs are available through breadboard-friendly headers or optional SMA connectors for RF work. Onboard 3.3 V regulation and I2C level shifting allow use with both 3 V and 5 V systems.\n\nKey Features\n\n\nSi5351A Clock Generator – I2C-controlled with onboard 25 MHz precision crystal reference\n\nWide Frequency Range – 8 kHz to 150+ MHz output\n\n3 Independent Outputs – Each output can be set to a different frequency\n\n3 Vpp Output – Via header pins or optional SMA connector for RF applications\n\nI2C Interface – Simple two-wire control with level shifting for 3 V and 5 V logic\n\n3–5 V Power – Onboard 3.3 V LDO regulator\n\n\nIdeal For\n\nReplacing fixed crystals and oscillators in prototypes\nRF and radio projects requiring precise clock signals\nTest and measurement equipment\nDigital signal processing and clock generation\n\n\nPackage Contents\n\n1× Adafruit Si5351A Clock Generator Breakout\n\n\nResources\n\nAdafruit Si5351 Clock Generator Guide & Arduino Library\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13863,"title":"Default Title","sku":"AF-2045","price":16.02,"on_sale":false,"in_stock":true,"available_quantity":88,"option1":"Default Title"}]}
