SI5335D-B05504-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335D-B05504-GM is a web-customizable, any-frequency, any-output quad clock generator and buffer manufactured by Skyworks Solutions. It synthesizes four non-integer-related frequencies up to 350 MHz using MultiSynth technology, ensuring 0 ppm frequency synthesis error. The device supports flexible input references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. It features independently configurable outputs supporting LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats with selectable supply voltages of 1.5, 1.8, 2.5, or 3.3 V. The core operates on a single supply of 1.8, 2.5, or 3.3 V.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B05504 suffix against the design requirements using the ClockBuilder Pro utility. Confirm that the 24-QFN package dimensions and thermal pad grounding meet the PCB layout specifications. Ensure the selected supply voltages align with the target load drivers.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with low jitter. Verify that the input reference signal matches one of the supported formats: 25/27 MHz crystal, CMOS, SSTL/HSTL, or differential. Check if the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) are compatible with the destination devices.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' suffix typically denotes specific electrical characteristics or package variations within the series, while the alphanumeric code defines the unique factory-programmed frequency plan and control pin assignments.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must be other Si5335 variants with identical factory programming. Generic clock generators cannot replicate the specific frequency synthesis and pin-control logic without reconfiguration.
