SI5335D-B05484-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335D-B05484-GM is a web-customizable, any-frequency, any-output quad clock generator and buffer. It synthesizes four non-integer-related frequencies up to 350 MHz using MultiSynth technology, ensuring 0 ppm frequency synthesis error. The device supports three independent pin-selectable configurations and features flexible input options including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL formats with independent voltage levels of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply (1.8, 2.5, or 3.3 V) within a 4x4 mm 24-QFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B05484 suffix via the official Skyworks ClockBuilder Pro tool or datasheet ordering section. Confirm that the pre-programmed pin assignments and frequency plans match the target design requirements before procurement, as this is a customized component.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a single device must replace multiple clock generators or buffers by utilizing its three independent configuration modes. Ensure the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) and signal formats (LVPECL, LVDS, etc.) are supported by the specific factory customization. Verify that the input reference source (crystal, CMOS, or differential) aligns with the configured input pins.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5335 family of highly flexible clock generators. The 'D' in the model number typically denotes a specific package or temperature range variant within the Skyworks portfolio, while the alphanumeric suffix indicates a unique factory-programmed configuration. It serves as a drop-in replacement for discrete crystal oscillators and multiple clock buffer ICs in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements require identical factory programming. Generic Si5335 devices can be used if reconfigured via ClockBuilder Pro, but pin compatibility and electrical characteristics must be verified. No other specific substitute part numbers are publicly confirmed for this exact configuration.
