The device accepts an external reference clock or crystal and generates four differential clock outputs, each of which is independently configurable to any frequency up to 350 MHz and select frequencies to 710 MHz. Using Skyworks Solutions patented MultiSynth technology, each output clock is generated with very low jitter and zero ppm frequency error. To provide additional design flexibility, each output clock is independently configurable to support any signal format and reference voltage. The Si5334 provides low jitter frequency synthesis with outstanding frequency flexibility in a space-saving 4 x 4 mm QFN package. The device configuration is factory or field programmed and, upon power up, the device will begin operation in the predefined configuration without user intervention. The device supports operation from a 1.8, 2.5, or 3.3 V core supply. Skyworks Solutions, Inc.
