SI5335D-B06026-GM

Overview

The SI5335D-B06026-GM 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 three independent pin-selectable configurations and features 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 operates on a single core supply (1.8, 2.5, or 3.3 V) within an ambient temperature range of –40 to +85 °C.

Feature Summary

• Four-output clock generator/buffer with 0 ppm frequency synthesis error via MultiSynth technology
• Supports three independent, user-assignable, pin-selectable device configurations
• Flexible input options: External crystal, CMOS, SSTL/HSTL, or differential signals
• Independently configurable outputs supporting LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL

Applications

• Ethernet switch/router
• PCI Express Gen 1/2/3/4 systems
• DSL jitter attenuation
• Processor and FPGA clocking
• Telecom line cards

Procurement Notes

Verify the specific factory configuration encoded in the B06026 suffix against system requirements. Confirm that the pin-selectable control functions (SSENB, RESET, OEB, FS) align with the hardware design. Ensure the required output voltage levels and drive strengths are supported by the customized firmware.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single package. Verify compatibility with the intended input reference source (crystal vs. driven clock). Check if the PCIe Gen 3 SRNS or Gen 4 jitter specifications meet the target application's compliance needs. Ensure the 24-QFN package footprint fits the PCB layout constraints.

Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' variant typically denotes specific performance or feature sets within the series, while the alphanumeric suffix defines the unique factory-programmed frequency plan and control pin mappings. It replaces multiple discrete oscillators and buffers in complex digital systems.

Replacement Considerations

Direct replacements require identical frequency plans and pin configurations. Generic Si5335 devices must be reconfigured via ClockBuilder Pro, which may alter control pin assignments. Verify that substitute parts support the same output formats and voltage levels.
