SI5335D-B04203-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335D-B04203-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 selection 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 Feature Summary

• Four independent output banks supporting any frequency (< 350 MHz) and format via MultiSynth fractional divider technology.
• Three user-assignable, pin-selectable device configurations allowing one device to replace multiple clock generators.
• Low phase jitter performance: 0.7 ps RMS typical in PLL mode; selectable loop bandwidths of 1.6 MHz or 475 kHz.
• Flexible input reference compatibility: External crystal, CMOS (10–200 MHz), SSTL/HSTL, and differential inputs (10–350 MHz).

Clock Generators, PLLs, Frequency Synthesizers Applications

• PCI Express Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking
• DSL jitter attenuation
• Broadcast video/audio timing

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B04203 suffix 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 output voltage levels and input reference type match the design specifications before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when four distinct, non-integer-related clock frequencies are required from a single source. Choose between the 1.6 MHz and 475 kHz loop bandwidth settings based on whether jitter attenuation or faster lock time is prioritized. Verify that the required output drive strength and voltage levels (LVPECL, LVDS, CMOS, etc.) are supported by the available output drivers.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' variant typically denotes specific package or thermal characteristics compared to other series members. The alphanumeric suffix defines the unique factory-programmed frequency plan and control pin assignments, distinguishing it from generic Si5335 models.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical frequency plans and pin configurations. Generic Si5335 devices cannot be used without reprogramming unless the pin functions match exactly. Alternative Skyworks parts like the Si5338 may offer similar functionality but require verification of pinout and feature compatibility.
