The Si5351A clock\ngenerator is an I2C controller clock generator. It uses the built-in precision\nclock to control multiple PLLs and watch dividers with I2C instructions. By\nsetting up the PLL and dividers, precise and arbitrary frequencies can be\ncreated. There are three independent outputs, and each can have a different\nfrequency. Outputs are 3 Vpp, either via a breadboard-friendly header or for\nRF work an optional Edge Launch SMA connector for output 1. To get you going\nquickly, Adafruit spun a tailor-made circuit board in the STEMMA QT form\nfactor, making it easy to connect. The STEMMA QT connectors on both sides are\ncompatible with the SparkFun QwiicI2C connectors. This allows you to make\nsolderless connections between your development board and the Si5351 or\nconnect to a variety of other sensors and accessories with a compatible cable.\nIntegrated 3.3V LDO and level switches mean it's ready for use with 3V or 5V\npower and logic. Si5351 Specifications: Produces up to 3 non-holistically\nconnected frequencies from 8kHz to 160MHz I2C custom configuration. Accurate\nfrequency synthesis at each output (0ppm error). Highly linear VCXO Low output\nperiod:100HP PP Configurable spectrum selectable at each output Operates with\na low cost, fixed frequency crystal: 25 MHz on board Supports static phase\noffset Programmable rise and fall time control. Glitchless frequency changes.\nExcellent PSRR eliminates external power supply filtering. Very low power\nconsumption. Adjustable output dela. PCIE Gen 1 compliant. Supports HCSL\ncompatible swing Dimensions: 25.3 x 17.7 x 4.7 mm.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eThis is an I2C control clock generator\u003c\/li\u003e\n         \u003cli\u003eIt uses the built-in precision clock to control multiple PLLs and watch dividers with I2C instructions\u003c\/li\u003e\n         \u003cli\u003eThree independent outputs, and each can have a different frequency\u003c\/li\u003e\n         \u003cli\u003eVery low power consumption\u003c\/li\u003e\n         \u003cli\u003eOperates with a low cost, fixed frequency crystal: 25 MHz on board\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":45749878030489,"sku":"de-B0BYF3B1WD","price":159.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/3148\/7385\/files\/de-B0BYF3B1WD.jpg?v=1775753287","url":"https:\/\/soundstores.net\/products\/adafruit-si5351a-clock-generator-with-stemma-qt-8-khz-to-160-mhz","provider":"SoundStore Australia","version":"1.0","type":"link"}
