SI5335D-B06047-GMR

Overview

The SI5335D-B06047-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. 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 operates on a single core supply of 1.8, 2.5, or 3.3 V within a –40 to +85 °C temperature range.

Feature Summary

• Four independent output banks supporting any frequency (< 350 MHz) with 0 ppm synthesis error via MultiSynth technology
• Configurable as clock generator or buffer with three pin-selectable device configurations
• Flexible input support: External crystal, CMOS (10–200 MHz), SSTL/HSTL, and differential (10–350 MHz)
• Low phase jitter (0.7 ps RMS typical) and selectable PLL loop bandwidths (1.6 MHz or 475 kHz)

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 MSAN/DSLAM/PON systems
• Processor and FPGA clocking

Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B06047, as this part is web-customized. Confirm that the required pin assignments for control functions (SSENB, RESET, OEB, FS) match the system design requirements defined in the ClockBuilder Pro utility. Ensure the selected output voltage levels and driver formats align with the target receiver specifications.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with precise frequency accuracy. Choose between the 1.6 MHz or 475 kHz loop bandwidth based on whether jitter attenuation or faster lock time is prioritized. Ensure the input reference type (crystal vs. driven input) matches the available system clock source. Verify that the 24-QFN package footprint and thermal characteristics fit the PCB layout constraints.

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 variant within the series, while the alphanumeric suffix indicates the unique factory-programmed configuration generated via Skyworks' ClockBuilder tool. It serves as a replacement for multiple discrete oscillators and buffers in complex digital systems.

Replacement Considerations

Direct replacements must be other Si5335 variants with identical factory configurations. Generic Si5335 parts will not function correctly without reprogramming. Verify compatibility with existing PCB footprints and ensure the new unit supports the same input/output voltage levels and signal formats.
