SI5335B-B06102-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335B-B06102-GMR is a web-customizable, any-frequency, any-output quad clock generator and buffer manufactured by Skyworks Solutions. It utilizes MultiSynth technology to synthesize four independent, non-integer-related frequencies up to 350 MHz with 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 highly configurable output drivers capable of LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats with independent voltage levels of 1.5, 1.8, 2.5, or 3.3 V. Packaged in a 4x4 mm 24-QFN with an exposed pad, it operates from a single core supply of 1.8, 2.5, or 3.3 V across a temperature range of –40 to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B06102 against the target design requirements using the ClockBuilder Pro utility. Confirm that the GMR suffix indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the selected output driver voltages and input reference types match the available power rails and source signals in the application circuit.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single package with low jitter specifications. Evaluate the loop bandwidth options (1.6 MHz or 475 kHz) based on whether jitter attenuation or fast lock time is prioritized. Ensure the input signal format (crystal, CMOS, or differential) aligns with the available reference source. Verify that the output load capacitance and drive strength requirements are met by the configurable output stages.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5335 belongs to Skyworks' MultiSynth family of programmable clock generators. This series replaces multiple fixed-frequency oscillators and buffers with a single customizable device. The B variant typically denotes specific electrical or packaging characteristics within the broader SI5335 product line, offering high integration for complex digital systems requiring precise timing.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. When replacing existing clock ICs, verify that the replacement supports the required number of outputs, frequency ranges, and jitter specifications. Check for compatibility with existing control pins and power supply configurations to ensure a drop-in solution without board redesign.
