SI5335A-B02062-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335A-B02062-GM is a web-customizable, any-frequency, any-output quad clock generator and buffer. It synthesizes four non-integer-related frequencies up to 350 MHz using MultiSynth technology for 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 support LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats 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 the -40 to +85 °C temperature range.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B02062 against the system requirements using the ClockBuilder Pro utility. Confirm that the GMR suffix indicates tape-and-reel packaging suitable for automated assembly. Ensure the selected input and output formats match the available pin functions and voltage domains defined in the datasheet electrical specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single device must replace multiple clock generators or buffers with varying frequency and format requirements. Choose between PLL mode for jitter attenuation or bypass mode for low additive jitter based on the application's noise sensitivity. Verify that the required output frequencies can be synthesized within the 350 MHz limit and that the power supply constraints align with the 1.8V, 2.5V, or 3.3V core supply options.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'A' variant typically denotes specific performance or feature sets within the series, while the numeric suffix defines the unique factory-programmed frequency plan. The device is designed to simplify system design by consolidating multiple clock sources into one customizable package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical frequency plans and pin configurations. Check if other Si5335 variants with different suffixes offer the same electrical characteristics but different packaging or configuration options. Ensure that any substitute maintains the same output drive strengths and input compatibility.
