SI5335D-B04217-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335D-B04217-GMR 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 a –40 to +85 °C temperature range.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B04217 suffix via the official Skyworks datasheet or ClockBuilder Pro tool. Confirm RoHS compliance and moisture sensitivity level requirements for the assembly process. Check current distribution availability as custom parts may have limited stock or longer lead times compared to standard inventory items.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when four distinct, non-integer-related clock frequencies are required from a single device. Ensure the input reference matches the supported formats (Crystal, CMOS, or Differential). Verify that the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) align with the target receivers. Use the ClockBuilder utility to generate the specific configuration file for the B04217 variant.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5335 family of highly flexible clock generators. The 'D' in the model number typically denotes a specific package or thermal variant within the series, while the 'GMR' suffix indicates tape-and-reel packaging. The Si5335 series is designed to replace multiple discrete clock oscillators and buffers, simplifying PCB layout and reducing component count in high-speed digital designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical frequency plans and pin configurations. Generic Si5335 variants may differ in output drive strength or power consumption. Verify compatibility with existing control pins (P1-P6) and ensure the replacement supports the same loop bandwidth settings (1.6 MHz or 475 kHz) for jitter performance.
