SI5335D-B05324-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335D-B05324-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 B05324 suffix against system requirements. Confirm that the required input reference type and output signal formats match the programmed settings. Ensure the PCB land pattern accommodates the 4 x 4 mm 24-QFN package dimensions and thermal pad connections.

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 (1.6 MHz or 475 kHz bandwidth) based on jitter attenuation needs. Verify that the target application supports the available output driver voltages (1.5V, 1.8V, 2.5V, or 3.3V) and logic families (LVPECL, LVDS, CMOS, etc.).

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 configuration. It replaces multiple discrete clock oscillators and buffers in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements require identical factory programming. Generic Si5335 variants may differ in output drive strength, loop bandwidth options, or supported input frequencies. Verify pin compatibility and electrical specifications before substituting other models in the Si5335A/B/C/D series.
