SI5335D-B05334-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335D-B05334-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 options 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 ordering suffix B05334 against the system requirements using the ClockBuilder Pro utility. Confirm that the required input source and output formats match the programmed settings, as the device is customized for specific frequency plans and control pin assignments.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single package with zero ppm error. Ensure the design utilizes the ClockBuilder Pro tool to define the exact frequency plan, loop bandwidth (1.6 MHz or 475 kHz), and spread spectrum parameters before ordering. Verify power supply constraints align with the 1.8 V, 2.5 V, or 3.3 V core supply options.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' in the model number typically denotes specific internal configuration parameters defined by Skyworks during manufacturing. It replaces multiple discrete clock oscillators and buffers, simplifying PCB layout and reducing bill-of-materials count in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-to-pin replacements within the same family require identical electrical characteristics and package dimensions (24-QFN). However, functional equivalence depends entirely on the custom frequency plan; substitute parts must be reconfigured via ClockBuilder Pro to match the original SI5335D-B05334-GM's specific output frequencies and control logic.
