SI5335B-B04883-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335B-B04883-GM is a web-customizable, any-frequency, any-output quad clock generator and buffer. It synthesizes four non-integer-related frequencies up to 200 MHz using MultiSynth fractional divider technology, ensuring 0 ppm frequency synthesis error. The device features four output banks supporting differential pairs or single-ended outputs with configurable formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and supports three independent pin-selectable configurations. Key electrical parameters include a maximum output frequency of 200 MHz, a typical phase jitter of 0.7 ps RMS, and an operating temperature range of –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B04883 against the system requirements before procurement. Confirm that the package type and moisture sensitivity level align with the assembly process. Check current availability status as custom-configured devices may have restricted supply channels.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four distinct clock frequencies are required from a single device with zero ppm error. Ensure the input reference source matches the supported formats: external crystal (25/27 MHz), CMOS (10–200 MHz), or differential/SSTL/HSTL (up to 350 MHz). Verify that the required output voltage levels (1.5, 1.8, 2.5, or 3.3 V) are compatible with the target receivers.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'B' variant typically denotes a specific frequency range capability (up to 200 MHz) compared to other family members like the 'C' or 'D' variants which may support higher frequencies. The suffix indicates a factory-programmed configuration generated via the ClockBuilder Pro utility.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Replacement requires verifying identical electrical specifications, pin compatibility, and the specific frequency plan programmed into the original component.
