SI5335D-B06026-GMR

Overview

The Skyworks SI5335D-B06026-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, ensuring 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 are configurable as LVPECL, LVDS, CML, HCSL, or CMOS 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 an ambient temperature range of –40 to +85 °C.

Feature Summary

• Four independent output banks supporting any frequency up to 350 MHz with 0 ppm synthesis error
• Three user-assignable, pin-selectable device configurations for replacing multiple ICs
• Flexible input reference: External crystal, CMOS (10–200 MHz), SSTL/HSTL, or Differential (10–350 MHz)
• Configurable output drivers: LVPECL/LVDS/CML (1–350 MHz), HCSL (1–250 MHz), CMOS (1–200 MHz), SSTL/HSTL (1–350 MHz)

Applications

• PCI Express Gen 1/2/3/4 common clock and jitter attenuation
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• DSL jitter attenuation and MSAN/DSLAM/PON systems
• Processor and FPGA clocking

Procurement Notes

Verify the specific ordering suffix -B06026-GMR against the manufacturer's current datasheet to confirm factory-programmed parameters. The 'GMR' suffix indicates tape-and-reel packaging. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure the configuration matches the target system requirements before procurement.

Selection Notes

Select this component when four distinct, non-integer-related clock frequencies are required from a single device. Choose between PLL modes (1.6 MHz or 475 kHz loop bandwidth) based on jitter attenuation needs for PCIe or DSL applications. Verify that the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) match the load specifications. Use the ClockBuilder Pro utility to generate the specific configuration file for the -B06026 part number.

Part Context

The SI5335D-B06026-GMR belongs to the Si5335 family of highly flexible clock generators. The 'D' in the model number typically denotes a specific package type or revision variant within the Skyworks portfolio, while the numeric suffix identifies the unique factory-programmed frequency plan. This series replaces multiple discrete oscillators and buffers, simplifying PCB layout and reducing component count in high-speed digital designs.

Replacement Considerations

Direct replacement requires matching the factory-programmed frequency plan. Generic Si5335 devices must be reconfigured via ClockBuilder Pro if the original settings are lost. Verify pin compatibility and thermal characteristics when substituting with other Si5335 variants.
