SI5335D-B06073-GM

Overview

The Skyworks SI5335D-B06073-GM 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 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. Outputs are independently configurable for LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL formats with selectable voltage levels of 1.5, 1.8, 2.5, or 3.3 V. It features three pin-selectable device configurations, spread spectrum control, and loss-of-signal alarms in a 4x4 mm 24-QFN package.

Feature Summary

• Four independent outputs supporting any frequency up to 350 MHz with 0 ppm synthesis error
• Configurable as clock generator or buffer with three user-assignable, pin-selectable device configurations
• Flexible input options: external crystal, CMOS, SSTL/HSTL, or differential signals
• Independent output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats

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 telecom line cards
• Processor and FPGA clocking systems

Procurement Notes

Verify the specific factory configuration encoded in the B06073 suffix via the official datasheet or Skyworks ClockBuilder Pro utility, as this part number represents a customized variant rather than a generic component. Confirm availability through authorized distributors, as lead times may vary for custom-programmed devices.

Selection Notes

Select this model when a fixed, pre-configured clock solution is required instead of a programmable blank device. Ensure the internal frequency plan matches the target system requirements, as the configuration is factory-set. Verify that the supported input reference types (crystal vs. external clock) align with the design architecture.

Part Context

This component belongs to the Si5335 family of highly flexible clock generators. Unlike standard programmable variants, the -B06073 suffix indicates a specific factory-programmed frequency plan and pin configuration. It serves as a drop-in replacement for multiple discrete oscillators and buffers in complex digital systems requiring precise timing.

Replacement Considerations

Direct substitution requires matching the exact frequency plan and output formats. Generic Si5335 devices can be reprogrammed but require external configuration tools. Verify pin compatibility and electrical characteristics against the original design specifications before implementation.
