The 1268974-SI5351A-B04489-GM is an I2C-programmable CMOS 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 with 0 ppm error and offers low output period jitter of less than 70 ps (typical). This clock generator operates using a low-cost, fixed-frequency crystal of either 25 or 27 MHz and allows for configurable spread spectrum at each output. It includes programmable rise and fall time control, glitchless frequency changes, and 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 Si5351A is suitable for various 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, accommodating different output requirements.
