SILICON LABS SI5335D-B03299-GM

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 Silicon Laboratories' 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.
