SI5335D-B04333-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335D-B04333-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 fractional divider 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 are configurable as LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL 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 4x4 mm 24-QFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B04333 against the system requirements using the ClockBuilder Pro utility. Confirm that the GMR suffix matches the required tape-and-reel packaging format for the assembly line. Ensure the selected loop bandwidth and output formats align with the verified datasheet specifications for the target application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source without integer relationships. Verify that the input reference signal type (crystal vs. driven) matches the design constraints. Check if the required output voltage levels and drive strengths are supported by the available driver options. Consider the thermal performance and power consumption limits for the intended operating temperature range.

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 electrical characteristics or package options within the series. The alphanumeric suffix defines the unique factory-programmed frequency plan and control pin assignments, distinguishing it from other Si5335 models with different timing configurations.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical frequency plans and pin assignments. Generic Si5335 devices cannot substitute this part without reprogramming via ClockBuilder Pro, which may alter control pin functions. Verify compatibility with existing PCB land patterns and ensure the replacement part supports the same input/output voltage levels and jitter performance requirements.
