SI5335D-B04178-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335D-B04178-GMR 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 references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. Outputs support LVPECL, LVDS, CML, HCSL, CMOS, and 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 of 1.8, 2.5, or 3.3 V within a –40 to +85 °C temperature range.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B04178 suffix via the official datasheet or ClockBuilder Pro tool, as this determines the exact frequency plan and pin functions. Confirm package type is 24-QFN and check current distribution availability through authorized Skyworks channels.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four distinct, non-integer-related clock frequencies are required from a single component. Ensure the design utilizes the web-based ClockBuilder Pro utility to define the specific frequency plan and control pin assignments before ordering, as the device is factory-customized.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' variant typically denotes specific performance or packaging characteristics within the series, while the alphanumeric suffix defines the unique factory-programmed configuration. It serves as a replacement for multiple discrete oscillators and buffers in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical frequency plans and pin configurations. Verify compatibility with existing PCB land patterns (24-QFN) and ensure that the replacement device supports the same input reference types and output voltage levels required by the target application.
