SI5335D-B05795-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335D-B05795-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 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 an ambient temperature range of –40 to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B05795 suffix against system requirements using the ClockBuilder Pro utility. Confirm that the pin-selectable control functions match the hardware design constraints. Ensure the 24-QFN package land pattern adheres to the recommended PCB layout guidelines for thermal and electrical performance.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with zero ppm synthesis error. Choose between the 1.6 MHz or 475 kHz PLL loop bandwidth based on jitter attenuation needs for PCIe or DSL applications. Verify that the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) are compatible with the target receiver inputs.

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 feature sets within the series, while the alphanumeric suffix defines the unique factory-programmed frequency plan and pin configuration. It replaces multiple discrete oscillators and buffers in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must be other Si5335 variants with identical pin-out and package dimensions. Verify that the substitute part's factory configuration matches the original frequency plan and control pin assignments. Generic Si5335 parts require reconfiguration via ClockBuilder Pro if the specific B05795 settings are not replicated.
