SI5335D-B06068-GM

Overview

The SI5335D-B06068-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 banks supporting any frequency synthesis up to 350 MHz with 0 ppm error
• Three independent, user-assignable, pin-selectable device configurations
• Flexible input options: External crystal, CMOS, SSTL/HSTL, or differential signals
• Configurable output drivers for LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats

Applications

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

Procurement Notes

Verify the specific factory configuration encoded in the B06068 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 configurations 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 loop bandwidth based on jitter attenuation needs for PCIe or DSL applications. Verify that the input reference type (crystal vs. buffered clock) matches the available system clock source.

Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' variant typically denotes specific performance characteristics or package options within the series. The unique alphanumeric suffix defines the proprietary frequency plan and pin configuration programmed during manufacturing via the ClockBuilder Pro utility.

Replacement Considerations

Direct replacements must be other Si5335 variants with identical pin configurations and electrical specifications. Verify that the replacement part supports the same output frequencies and formats. Note that ordering suffixes determine the internal configuration; generic Si5335 parts will not function without matching the specific programmed settings.
