SI5335C-B05010-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5335C-B05010-GMR is a web-customizable, any-frequency, any-output quad clock generator and buffer from 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 flexible input references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. Outputs are independently configurable for LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL formats with selectable supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It features low phase jitter of 0.7 ps RMS, two selectable PLL loop bandwidths (1.6 MHz or 475 kHz), and 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 B05010 suffix via the official datasheet or Skyworks ClockBuilder Pro utility, as this part number represents a custom program. Confirm that the required pin-selectable configurations and output voltage levels match the system design requirements before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single device must replace multiple crystal oscillators or clock generators by providing four distinct, non-integer-related frequencies. Ensure the input reference type (crystal, CMOS, or differential) matches the available source. Verify that the required output driver formats and voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) are supported by the target loads.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5335C-B05010-GMR belongs to the Si5335 family of highly flexible clock generators. The 'C' indicates a specific configuration variant, while 'GMR' denotes the tape-and-reel packaging format. This series is designed to simplify system design by consolidating clock generation, buffering, and level translation into one small 4x4 mm 24-QFN package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacement requires matching the exact frequency plan and pin configuration. Generic Si5335 variants may not have the same factory-programmed settings. Verify compatibility with existing PCB land patterns and ensure the new part supports the required output voltage levels and input reference types.
