SI5335D-B05861-GMR

Overview

The SI5335D-B05861-GMR 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 fractional divider technology, ensuring 0 ppm frequency synthesis error. The device supports flexible input references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. It features independently configurable outputs supporting LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats with selectable supply voltages of 1.5, 1.8, 2.5, or 3.3 V. Key electrical parameters include a core supply current of 45 mA in PLL mode and 12 mA in buffer mode, operating on a single supply of 1.8, 2.5, or 3.3 V.

Feature Summary

• Four independent output banks capable of synthesizing any frequency up to 350 MHz with 0 ppm error
• Supports three independent, pin-selectable device configurations for multi-function replacement
• Low phase jitter performance with typical RMS values of 0.7 ps in clock generator mode
• Flexible input options including crystal, CMOS, SSTL/HSTL, and differential signals

Applications

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

Procurement Notes

Verify the specific factory configuration associated with the B05861 suffix via the official Skyworks ClockBuilder Pro tool or datasheet ordering section. Confirm package type and temperature range compliance before integration. Ensure reference designators match the customized pinout defined by the manufacturer for this specific part number variant.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source without integer relationships. Verify that the required output voltage levels (1.5V to 3.3V) align with the target load drivers. Check if the available loop bandwidth settings (1.6 MHz or 475 kHz) meet the specific jitter attenuation requirements of the application.

Part Context

This part 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 Skyworks portfolio, while the alphanumeric suffix indicates a unique factory-programmed configuration. It serves as a drop-in replacement for multiple discrete oscillators and buffers in complex digital systems.

Replacement Considerations

Direct replacements must be other Si5335 variants with identical pin-compatible configurations. Verify that the substitute part number has the same output frequency plan and voltage levels. Generic Si5335 parts may require reconfiguration via ClockBuilder Pro if the factory settings differ.
