SI5335D-B05998-GM

Overview

The SI5335D-B05998-GM is a web-customizable, any-frequency, any-output quad clock generator and buffer manufactured by 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 configurable as LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL 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-output clock generator/buffer synthesizing any frequency up to 350 MHz with 0 ppm error
• Three independent, user-assignable, pin-selectable device configurations
• Flexible input support: External crystal, CMOS, SSTL/HSTL, and differential signals
• Configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats

Applications

• PCI Express Gen 1/2/3/4 common clock generation
• Ethernet switch/router clocking
• Processor and FPGA clocking
• DSL jitter attenuation
• Broadcast video/audio timing

Procurement Notes

Verify the specific factory configuration encoded in the B05998 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 signal formats match the available driver options for this specific part number.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with zero ppm error. Choose between the 1.6 MHz or 475 kHz PLL loop bandwidth based on jitter attenuation needs for PCIe or DSL applications. Verify that the input reference type (crystal vs. driven clock) matches the available input pins and configuration 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 pin configuration. It replaces multiple discrete oscillators and buffers in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Replacement requires matching the exact frequency plan and pin configuration via Skyworks ClockBuilder Pro utility or verifying equivalent functionality from other vendors if the custom configuration allows.
