SI5335D-B04595-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335D-B04595-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 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 an ambient temperature range of –40 to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B04595 suffix against system requirements. Confirm that the 24-QFN package dimensions and thermal pad grounding meet PCB layout specifications. Ensure the selected core and output supply voltages align with the target application's power rails before integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with zero ppm error. Choose between PLL modes based on jitter attenuation needs: 1.6 MHz bandwidth for high-speed interfaces like PCIe, or 475 kHz for DSL applications. Verify that the required output voltage levels (1.5V to 3.3V) are supported by the available VDDO supplies.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. Unlike fixed-frequency oscillators, it allows for custom frequency plans via the ClockBuilder Pro utility. The 'D' variant typically denotes specific performance characteristics or input/output capabilities within the broader Si5335 product line, designed to replace multiple discrete clock components.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. When replacing legacy oscillators, ensure the new design accommodates the programmable nature of the Si5335 and verifies compatibility with the specific frequency plan defined by the B04595 suffix.
