SKYWORKS SI5335A-B08002-GMR

The Si5335 is a highly flexible clock generator capable of synthesizing four completely non-integer-related frequencies up to 350 MHz. The device has four banks of outputs with each bank supporting one differential pair or two single-ended outputs. Using Skyworks Solutions' patented MultiSynth fractional divider technology, all outputs are guaranteed to have 0 ppm frequency synthesis error regardless of configuration, enabling the replacement of multiple clock ICs and crystal oscillators with a single device. The Si5335 supports up to three independent, pin-selectable device configurations, enabling one device to replace three separate clock generators or buffer ICs. To ease system design, up to five user-assignable and pin-selectable control pins are provided, supporting PCIe-compliant spread spectrum control, master and/or individual output enables, frequency plan selection, and device reset. Two selectable PLL loop bandwidths support jitter attenuation in applications, such as PCIe and DSL. Through its flexible ClockBuilder Pro web configuration utility, factory-customized, pin-controlled devices are available in two weeks without minimum order quantity restrictions.
