SI5335D-B06068-GMR

Overview

The SI5335D-B06068-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 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 supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It features low phase jitter of 0.7 ps RMS, two selectable PLL loop bandwidths (1.6 MHz or 475 kHz), and up to five user-assignable pin functions.

Feature Summary

• Four independent output banks supporting any frequency (< 350 MHz) with 0 ppm synthesis error
• Configurable as clock generator or buffer with selectable PLL loop bandwidths (1.6 MHz or 475 kHz)
• Supports multiple output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, HSTL
• Up to three independent, pin-selectable device configurations

Applications

• PCI Express Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• DSL jitter attenuation and telecom line cards
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B06068 via the official datasheet or ClockBuilder Pro utility. Confirm that the required pin assignments and control logic match the system design before procurement, as this is a customized component.

Selection Notes

Select this part when a single device must replace multiple clock generators or buffers with distinct frequency requirements. Ensure the input reference source matches the supported formats (crystal, CMOS, differential). Verify that the required output voltage levels (1.5V to 3.3V) are compatible with the load devices.

Part Context

This component belongs to the Si5335 family of highly flexible clock generators. The 'D' in the model number typically denotes a specific performance grade or feature set within the series, while the suffix indicates the unique factory programming. It is designed to simplify system design by consolidating multiple clock sources into one package.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Replacement requires a new custom configuration from Skyworks Solutions using the same base Si5335 device.
