SI5335D-B15677-GM

Overview

The SI5335D-B15677-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 options 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 (1.8, 2.5, or 3.3 V) within an ambient temperature range of –40 to +85 °C.

Feature Summary

• Four output banks supporting any frequency up to 350 MHz with 0 ppm synthesis error

• Flexible input reference: External crystal, CMOS, SSTL/HSTL, or differential
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V

Applications

• Ethernet switch/router
• PCI Express Gen 1/2/3/4
• Processor and FPGA clocking
• Telecom line cards
• Fibre Channel, SAN

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact factory-programmed configuration, as the base part number refers to the generic device family. Confirm package type and compliance status via the official datasheet before procurement.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with zero ppm error. Ensure the design utilizes the ClockBuilder Pro utility for customization. Verify that the required output formats (LVPECL, LVDS, etc.) and voltage levels match the available driver capabilities.

Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' in the model number typically denotes specific performance or feature variations within the family, while the alphanumeric suffix indicates the unique factory programming configuration.

Replacement Considerations

Direct replacements must be other Si5335 variants with identical factory programming. Cross-model substitution requires re-configuration via ClockBuilder Pro and verification of electrical compatibility.
