Skyworks Solutions, Inc. Integrated Circuits (ICs) - Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers SI5351C-B08932-GM

The SI5351C-B08932-GM is an I2C-programmable clock generator capable of producing up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz. It features a highly linear voltage-controlled crystal oscillator (VCXO) and supports an optional clock input (CLKIN). The device ensures exact frequency synthesis at each output with 0 ppm error and offers low output period jitter of less than 70 ps (typical). This clock generator operates from a low-cost, fixed-frequency crystal of either 25 or 27 MHz and includes configurable spread spectrum capabilities at each output. It provides separate voltage supply pins for level translation, with core voltage options of 2.5 or 3.3 V and output voltage options of 1.8, 2.5, or 3.3 V. The SI5351C also supports static phase offset and programmable rise/fall time control, making it suitable for various applications, including audio/video equipment, networking, and handheld instrumentation. Available in multiple package types, including a 20-QFN (4x4 mm) with eight outputs, the SI5351C is designed for cost-sensitive applications, replacing traditional crystals and PLLs while maintaining reliable performance.
