Skyworks Solutions, Inc. Clock and Timing IC SI5351A-B05950-GT

The SI5351A-B05950-GT is an I2C-programmable clock generator capable of generating 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 exact frequency synthesis with 0 ppm error at each output. The device operates from a low-cost, fixed-frequency crystal of either 25 or 27 MHz and includes an optional clock input (CLKIN). The SI5351A offers low output period jitter of less than 70 ps peak-to-peak and allows for configurable spread spectrum at each output. It has separate voltage supply pins for core and output voltages, supporting levels of 2.5 or 3.3 V for core and 1.8, 2.5, or 3.3 V for output. The product is designed for low power consumption and includes features such as glitchless frequency changes and programmable rise/fall time control. This clock generator is suitable for a variety of applications, including audio/video equipment, gaming, networking, and handheld instrumentation, making it a versatile choice for engineers looking to replace traditional crystal oscillators and PLLs in cost-sensitive designs.
