Skyworks Solutions, Inc. Clock and Timing IC SI5351B-B04745-GM

The SI5351B-B04745-GM is an I2C-programmable clock generator that can produce 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 is designed for low output period jitter, typically less than 70 ps peak-to-peak, and offers glitchless frequency changes. This clock generator operates from a low-cost, fixed-frequency crystal of either 25 or 27 MHz and provides configurable spread spectrum options at each output. It includes separate voltage supply pins for core and output voltages, allowing for level translation, with core VDD options of 2.5 or 3.3 V and output VDDO options of 1.8, 2.5, or 3.3 V. The device is characterized by excellent power supply rejection ratio (PSRR) and low power consumption. The SI5351B is suitable for a variety of applications, including audio/video equipment, gaming, printers, handheld instrumentation, and networking devices. It is available in multiple package types, including 10-MSOP, 16-QFN, and 20-QFN, making it versatile for different design requirements.
